Why Dowel Bars Deserve More Attention?

In concrete road construction, one small mistake can turn into massive repair costs. And often, that mistake is ignoring dowel bars—the unsung heroes of load transfer. These simple steel rods are often overlooked, but they’re essential in keeping concrete pavements stable, crack-free, and cost-effective in the long run.

If you’re in infrastructure or road projects, understanding the correct use of dowel bars in concrete can make or break your pavement’s durability.

What Are Dowel Bars and What Do They Do?

Dowel bars are cylindrical steel rods placed across transverse joints in concrete pavements. They ensure that loads are transferred from one concrete slab to the next, allowing for smooth traffic movement without putting excessive pressure on any single slab.

This mechanism—known as load transfer in pavements—prevents slab cracking, corner breaking, and uneven surfaces, especially under heavy vehicles.

Technical Specifications of Dowel Bars (India Standards)

In Indian road construction, dowel bars generally follow these guidelines:

Diameter: 25 mm to 38 mm

Length: 450 mm to 600 mm

Spacing: 300 mm to 350 mm center-to-center

Coating: Epoxy or stainless steel to resist corrosion

Placement: Aligned perfectly in the middle of the slab thickness

Standards followed include:

IRC:58 for pavement design

IS:456 for concrete structure practices

Incorrect dimensions or poor alignment can cause joint locking, defeating the purpose of load transfer altogether.

Benefits of Dowel Bars in Concrete Pavements

Reduces edge cracking under load

Minimizes maintenance costs over time

Improves ride quality and surface level

Enhances load-sharing between slabs

Complies with modern engineering codes

For highway projects, industrial zones, airports, and even smart city roads, dowel bars offer both performance and ROI.

Common Mistakes to Avoid in Dowel Bar Placement

Misaligned dowel bars cause joint locking.

Wrong bar size reduces effectiveness.

Inadequate corrosion protection leads to early failure.

Poor concrete compaction around bars leads to voids.

Use dowel bar baskets, proper templates, and level indicators during installation.

Real-World Example: Long-Lasting Urban Roads

A smart city project in central India faced early pavement failures due to missing dowel bars. Upon redesign with proper dowel bar placement in roads, maintenance dropped by 42%, and surface life increased by 5+ years—all by investing a small amount in the right steel rods.

Engineering Best Practices for Dowel Bars in Rigid Slabs

Dowel bars in rigid pavement are the unseen heroes of structural durability. Found across expressways, airfields, industrial yards, and bus lanes, they’re vital for smooth load transfer between concrete slabs. But their success isn’t based on guesswork—precision is everything. Coupled with innovations like construction rings and Super Rings, dowel bars have evolved from simple cylindrical inserts to engineered components in rigid pavement systems.

From the very beginning of slab installation, construction rings play a foundational role. These elements help maintain proper spacing, alignment, and position during placement, preventing misalignment that could otherwise lead to joint failure. Meanwhile, Super Rings—known for their high tolerance and performance in extreme loads—deliver unmatched holding power, particularly in high-traffic zones. These two elements, when integrated properly, elevate the lifespan and integrity of rigid pavement structures.

Why Proper Load Transfer Can’t Be Overlooked

Concrete expands and contracts. It cracks. It shifts. That’s inevitable. Without an effective load transfer system, these natural changes cause differential settlement—making one slab sink while the next holds. The result? A bumpy ride, early cracking, and costly maintenance. Dowel bars in rigid pavement solve this problem by linking adjacent slabs, distributing the wheel load evenly, and reducing stress concentration on the joint.

But even the best dowel bar won’t work if placed incorrectly or without adequate alignment support. This is where construction rings step in. These devices ensure precise positioning during installation, especially in repetitive paving operations. Super Rings, on the other hand, are engineered to keep the dowel in optimal alignment even when subjected to heavy vibration or shifting during the pour. Together, these components form a fail-proof trio.

Installation Techniques That Define Performance

Surface Preparation and Alignment

The foundation of rigid pavement success starts with a clean, compacted sub-base. Once formwork is in place, construction rings are used to hold dowel bars exactly perpendicular to the joint face. Misalignment by even a few degrees can compromise load transfer and cause binding.

Joint Width and Embedment Length

The spacing of dowel bars typically ranges from 300 mm to 400 mm, depending on load class. Embedment length is equally critical—ideally half the length of the dowel sits in each slab. The role of Super Rings becomes evident here, locking the bar into perfect position during curing, preventing any shift due to weight or concrete flow.

Benefits That Go Beyond Basics

Long-Term Pavement Performance Proper dowel installations drastically reduce faulting at joints, leading to smoother surfaces and fewer maintenance disruptions.

Cost Efficiency Fewer repairs mean less downtime and resource allocation. Integrating Super Rings early on may seem like a minor added cost, but they pay off in lifecycle extension.

Sustainability and Resource Optimization With longer service life, pavements need fewer reconstructions. Fewer reconstructions mean reduced use of concrete, fuel, labor, and logistics—a win for both budgets and the environment.

Common Pitfalls and How to Avoid Them

1. Misaligned Bars

A slightly tilted dowel may create restraint instead of freedom of movement. Using construction rings during placement eliminates such misalignments.

2. Floating During Concrete Pour

The buoyancy of steel in fluid concrete is often underestimated. This is why Super Rings—with their strong anchoring capability—are essential.

3. Inadequate Bar Length or Diameter

Cutting corners on dowel specs often leads to cracked slabs. Always consult pavement design loads and use recommended diameters.

Final Thoughts: Engineering That Lasts

Dowel bars in rigid pavement aren’t just optional accessories—they are a critical design element. When paired with construction rings for alignment and Super Rings for stability, they offer unparalleled longevity and performance in rigid slab systems. These practices aren’t just “best”; they’re essential. Long-lasting roads, safer industrial platforms, and stronger airport runways all begin with what lies beneath—precise, engineered connection.

How Wellness Retreats in Rishikesh Integrate Somatic Healing and Ayurveda

Wellness retreats in Rishikesh are steadily evolving beyond yoga and meditation, offering a more layered, transformative experience. Within the first few days at a healing retreat in Rishikesh or any wellness retreat near Rishikesh, visitors encounter therapies rooted in body-focused science and ancient Indian medicinal systems that align structural well-being with emotional regulation.

The Hidden Engineering of Human Recovery

Somatic healing works like structural retrofitting—strengthening what's already built by addressing unnoticed stress fractures. It draws from neurobiology and trauma-informed science, helping participants access deep muscle memory and nervous system patterns. At healing retreats in Rishikesh, somatic protocols often resemble re-calibration techniques used in structural engineering—measured, intentional, and non-invasive, yet profoundly impactful.

Ayurveda as the Biological Maintenance System

While somatic healing fine-tunes the nervous system, Ayurveda addresses the entire bodily infrastructure. Daily detox routines like Panchakarma, medicated oil therapies, and tailored herbal plans function similarly to preventative maintenance schedules in infrastructure management. A wellness retreat near Rishikesh often begins with Nadi Pariksha—a diagnostic method assessing bio energies—allowing for customized treatment flows that stabilize the body’s foundation, much like reinforcing materials based on soil reports.

Movement as Micro-adjustment

Movement-based therapies such as Katichakrasana, Somatic Yoga, and Myofascial Release serve as the dynamic joints in the healing structure. Just as expansion joints in concrete allow for controlled flexibility, these practices grant the body space to adjust, recalibrate, and redistribute tension. Healing retreats in Rishikesh incorporate such techniques to rewire chronic stress loops embedded within the muscular and skeletal systems.

Integrated Systems Yield Sustainable Wellness

Much like sustainable building projects rely on synergy between structural integrity, materials, and systems, wellness retreats in Rishikesh combine disciplines to build resilience. Somatic sessions often precede Ayurvedic detox, ensuring that physical release prepares the body to absorb herbal remedies. Breathing practices follow physical treatments, much like aeration improves concrete setting—each step builds upon the last for long-term results.

Personalization Based on Structural Feedback

No two buildings react the same way to load-bearing stress, and neither do bodies. At a wellness retreat near Rishikesh, practitioners continuously monitor guests’ progress through prakriti (constitution) assessments and somatic feedback. Protocols adapt in real-time, just as engineering teams adjust material application based on live-site analysis.

Why Civil Engineers Are Observing Wellness Protocols

The crossover between wellness science and infrastructure engineering is gaining traction. Just as a bar dowel transfers load and maintains structural continuity across concrete joints, somatic healing and Ayurveda create neuro-muscular continuity across emotional trauma and physical stress. Decision-makers in civil and structural sectors have begun drawing parallels between human wellness systems and high-resilience materials science.

Selecting the Right Retreat is Like Choosing the Right Reinforcement System

Not all wellness retreats in Rishikesh deliver the same integrity. Just as the wrong binding wire can compromise a reinforced slab, choosing a retreat lacking licensed Ayurvedic doctors or trauma-informed somatic therapists may dilute results. Checking lineage, certification, and integration between practices is vital—engineers wouldn’t risk low-tensile dowels; neither should anyone seeking authentic healing.

Conclusion: When Structure and Soul Align

Healing, when approached scientifically and systematically, goes beyond relaxation. The blend of somatic healing and Ayurveda, as seen in many healing retreats in Rishikesh, creates a multi-layered reinforcement strategy—one that heals, restores, and fortifies. A well-selected wellness retreat near Rishikesh becomes more than a destination; it becomes a restoration site for the body’s core framework.

FAQs

1. How is somatic healing different from yoga? Somatic healing focuses on nervous system regulation and trauma release through micro-movements and body awareness rather than stretching or postures.

2. What is the role of Ayurveda in modern wellness retreats? Ayurveda customizes internal detox, nutrition, and herbal therapies to support systemic healing, much like a structural analysis leads to targeted reinforcement.

3. Can engineers or contractors benefit from these retreats? Yes. These programs offer physical recovery, stress recalibration, and structured systems thinking, which parallel engineering workflows.

Dowel Bar

Dowel bars stand for quick metallic bars that are commonly applied in concrete pavements to preserve a mechanical connection amongst slabs without preserving the horizontal joint motion restricted. The bars are furnished amongst concrete slabs to transmit the masses some of the slabs and facilitate any horizontal motion because of expansion.

They make the weight transmission higher via way of means of facilitating the depart slab to presume a number of the weight previous to the weight is implementing over it practically. As a result, the joint deflection and strain are minimized withinside the technique and depart slabs.

Dowel bars are organized on the transverse joints of concrete pavement and are concerned withinside the partial transmission of wheel load from one slab to its adjacent slab.

Loads bars are improved from an RCC member with the purpose that withinside the destiny while the RCC member is enlarged, the reinforcement of the extension is hooked up with those bars.

The duration of dowel bars in compression stays forty five instances bar dia and in anxiety it's far retained as fifty two instances the bar dia.

Concrete pavement road structures?

Concrete pavements, also known as rigid pavements, have a structured design to ensure they can bear heavy traffic loads and provide a durable surface. Here's an overview of the typical structure of a concrete pavement:

1. Subgrade: This is the natural soil prepared and compacted to provide a stable foundation for the pavement. Proper compaction and stabilization are essential to prevent settlement and maintain the pavement's integrity.

2. Sub-base: A layer of granular material, such as gravel or crushed stone, placed above the subgrade. The sub-base layer provides additional support, improves drainage, and helps distribute loads more evenly to prevent stress concentration on the subgrade.

3. Base Course: An optional layer of high-quality granular or stabilized material (e.g., cement or lime-stabilized) that offers additional structural support and further load distribution. This layer is particularly useful in areas with poor subgrade conditions.

4. Separation Layer (optional): In some designs, a separation layer or membrane, such as a geotextile fabric, is placed between the base/sub-base and the concrete slab to prevent moisture movement and enhance load distribution.

5. Concrete Slab: The main structural component of the pavement, made of Portland cement concrete. The slab is designed to bear traffic loads and provide a durable, smooth surface. The thickness of the concrete slab depends on the expected traffic load and environmental conditions. Reinforcement (e.g., steel bars or mesh) may be included to enhance strength and control cracking.

6. Joints: Concrete pavements include various types of joints to control cracking and accommodate expansion and contraction:

- Transverse Joints: Placed at regular intervals to control cracking caused by temperature changes and shrinkage.

- Longitudinal Joints: Used to control cracking along the length of the pavement.

- Expansion Joints: Allow for expansion and contraction due to temperature changes.

- Dowel Bars: Installed across transverse joints to transfer loads between slabs and maintain alignment.

- Tie Bars: Used in longitudinal joints to hold adjoining slabs together and prevent separation.

7. Surface Treatment (optional): A surface treatment or texture, such as a broom finish or grooving, is sometimes applied to the concrete slab to improve skid resistance and reduce surface wear.

They start thinking about it reframe the walls out on the inside with wood frame as you probably should use metal it's a lot faster it is actually and people use the right tools to take seconds to put it takes like a millisecond to put the metal together you do it too you screw it and screw it but you can't screw into the concrete he's told it back you figured out something he's pretty smart and you put the metal studs in the ceiling is the roof be concrete and you have all these metal stud companies and they do all these buildings and there's no buildings being built so he's trying to thinking it was a good idea and it's looking at doing it he knows you know how to design it it says you put in beds in but you don't have to you do for connecting it but you don't have to put in bed soon for utilities you've done all sorts of concrete tilt up I said yeah that's true it doesn't feel good about it unless they're steal init. And put the rebar in the panel and you put the connector touch to the rebar and it goes oh that's how and you dial it up and you put the concrete panel into the dowel and there's easier connection to spend that would make it extremely strong you don't need a few dolls by the way on a wall two or three on a 20-foot wall start looking at it and it's true that's because you have a thickened slab and the doll can be pretty big in you epoxy it so he started thinking of this you can do it in place it takes a little while but it takes less time to do well you can put the bar off and put a certain measurement and you make the whole bigger and use epoxy grout so you like that I seen the epoxy garage doesn't move doesn't break and just drop it into epoxy grout seal and also need to figure it out something this doesn't sound hard and Lily did it all over the place I don't know what she made tomorrow you heard you say is Donald the bottom you have a closure at the Tom angel and a closure please at the middle and you weld it and that should be all you need they're not going to be heavy it's lightweight concrete and trained and it's a higher percent cuz you can achieve it with precast and he thought this why can't I use those on the vertical wall I said does it cost more to make you don't have to it can be heavy I mean you see them you walls are heavy and they're more apt to break than concrete since but if it falls it falls in a big slab together panels

Dowel Bars in Heritage Site Restorations—A New Preservation Standard

Dowel bars, once limited to road construction and heavy-duty industrial flooring, are now rewriting the restoration rules for heritage architecture. Their seamless integration with robust materials like TMT saria bars and reinforcement solutions from trusted TMT bar manufacturers is quietly establishing a new preservation benchmark. As the conservation industry evolves, structural reliability is no longer a luxury—it’s a non-negotiable standard. And dowel bars are at the center of this quiet revolution.

From crumbling colonial buildings to ancient temple courtyards, structures born in a different era are demanding more than aesthetic touch-ups. What lies beneath—the skeletal integrity—defines whether a site can survive for another century. Here, TMT saria bar proves invaluable, offering reinforcement with strength and ductility. But when it comes to load transfer and stability between aged slabs and restored surfaces, dowel bars are irreplaceable.

Why Heritage Sites Need More Than Cosmetic Restoration

Centuries-old buildings face multiple challenges—soil settlement, climate damage, layered renovations, and structural fatigue. Often, these vulnerabilities manifest not on the surface, but in the core joints where time has eaten into cohesion. Surface repairs may offer a visual revival, but without embedded support, even the grandest restorations fail within decades.

Dowel bars address this need by acting as load-transfer anchors, especially in horizontal joints, pavements, or between floor panels. In sites where restoration teams must retain original materials, dowel bars provide a subtle but powerful solution. They do not interfere with the aesthetic, yet they introduce critical reinforcement. Combined with the TMT saria bar, the structural synergy is unparalleled. Reputed TMT bar manufacturers now offer specialized variants tailored for restoration-grade performance, minimizing corrosion risk while maximizing lifespan.

Functionality and Precision in Fragile Structures

Precision is not just technical—it's a moral responsibility in heritage work. Every intervention must be calculated, respectful, and as reversible as possible. Dowel bars provide this flexibility. Inserted between slabs or walls to connect new components with the old, they allow for controlled movement while maintaining alignment.

In earthquake-prone zones or high-traffic heritage sites, this functionality becomes crucial. Unlike continuous reinforcement, dowel bars don’t create unnecessary tension zones. Instead, they absorb movement, stabilize vertical shifts, and prevent differential settling. Their compatibility with TMT Saria bars adds to their merit, especially when working with hybrid reinforcement designs. Today, leading TMT bar manufacturers offer bars with surface treatments and rib patterns optimized for bonding with dowel-supported joints.

Bridging Time with Technology

Modern tools are enabling restoration experts to go beyond surface conservation. Ground-penetrating radar, digital modeling, and material mapping are identifying weak joints that traditional methods overlook. Here’s where dowel bars step in as the quiet saviors—placed with millimeter precision, guided by scans, and executed without visual disruption.

These bars create bridges between the past and the future. Whether it’s connecting weathered marble floor panels or anchoring restored beams into century-old stone, they work silently behind the scenes. Coupled with TMT saria bar, which continues to serve as the structural backbone, dowel-reinforced sites gain newfound resilience—unseen but unfailing.

A Silent Innovation That’s Here to Stay

No buzzwords. No sweeping claims. Just a simple, steel-forged solution working quietly beneath the surface. That’s the magic of dowel bars. Their unassuming design masks a future-proof capability to protect, preserve, and reinforce where traditional methods fall short.

When paired with the unmatched tensile performance of TMT saria bar and the advanced metallurgy offered by established TMT bar manufacturers, they form a restoration system that respects the past while securing the future. As more heritage engineers and planners shift toward scientifically backed methods, dowel bars are poised to define the new standard in structural preservation.

For those entrusted with restoring the irreplaceable, the choice is no longer just aesthetic—it’s structural. And in that decision, dowel bars deserve their place as guardians of heritage.

What are the various types Steel Bars

Brisbane steel bar is also an essential component for buildings on a much smaller scale, and can be found in many houses, car parks, schools, high risers, factories and airports. The steel in these structures can be in the form of steel framing within the building walls while it can also used on roofs and as cladding for exterior walls. Construction is one of the most important steel-using industries, and accounts for the use of more than 50% of global steel production. Some of the most famous structures in the world such as the Statue of Liberty, the Brooklyn Bridge and the Empire State Building rely on Brisbane steel bar to provide their structural strength.

Reinforcing Brisbane steel bar- Can consist of plain, round or ribbed reinforcing steel depending on the application. Metalcorp can supply a full range of reinforcing bar products, sourcing reinforcing fabric and bar products from ACRS accredited suppliers (see ACRS for further details), ensuring you have access to the best material made to Australian Standards.

Reinforcing Steel – Plain Round Bars - reinforcing Steel can be a simple round low carbon section for use in simple reinforcing construction. Commonly used to manufacture ligatures used to separate top and bottom layers of mesh in concrete slabs, or as dowel bars for joining concrete sections in pavement. An example would be R10 or R12.

Reinforcing Steel – Deformed Bars- Deformed bar is used where extra reinforcing is required to fabric sheets or trench mesh. A typical length would be called Y12 or Y16 or DB for deformed bars. Lengths can range from 6m to 9m and longer on application. Specifically produced for use in domestic swimming pool construction, where manipulability to bend and shape is needed. An example would be S10 or S12.

Beams- A universal beam has an ‘I’ cross section with its main application in the structural frames of sheds and large buildings. It is also used in applications where significant weight needs to be carried by semi-trailer chassis or where large spans need to be achieved as in bridges.

 1.    Light universal beams range from 150 UB through to 410 UB.

2.    Heavy universal beams include 460 UB through to 610 UB.

 Channels- Common uses are house floor joists, semi-trailer rails and industrial stair frames to name a few. Light Black channels include 150 PFC through to 250 PFC while heavy channels range from 300 PFC through to 380 PFC. Lengths may be supplied from 9 to 18 metres in increments of 1.5 metres. Channels are often called ‘C’ or ‘PFC’ sections. As with beams, channels are mainly used in structural applications.

 Columns- Light universal columns range from 100 UC to 200 UC. Heavy universal columns range from 250 UC to 310 UC. Length range is available from 9 through to 18 metres in 1.5 increments however, 100 UC are only available in 9, 12 and 15 metre lengths. Universal Columns, as with Beams and Channels, are mainly used in structural applications. As with beams, the cross section of the product has an ‘I’ shape.

ERW Line pipes- The size range is from 114mm OD to 610mm OD and is available in stock lengths of 12m. ERW large diameter circular pipe is used in structural applications mainly for columns, bollards, and water reticulation for the fire industry.

Your builder will need to resolve these contractual issues with the supplier/manufacturer of the product. The use of steel bar not complying with the standard as advertised may be a contractual breach for which building owners could seek remedies through their builder.

Kew Courtyard House in Melbourne

Design: Drawing Room Architecture

Location: Kew, Melbourne, Victoria, Australia

Kew Courtyard House

Kew Courtyard is a forever home for a creative couple. The house supports their mutual love of entertaining, art, gardening and mid century architecture. The site was a previously subdivided one being only 7m wide yet over 45m long with north following the long side of the site.

To create a two bedroom, one generous study, two bathroom home with a sunny kitchen & dining and a separate living room, planning was key. Living rooms where placed to get lots of natural light and garden views, meaning a central courtyard needed to be carved out. This courtyard would be the lungs, green and light lantern to the ground floor living areas.

The study was located on the ground level also with street views. The two bedrooms are on the first floor were they have private leafy views over surrounding rooftops.

What was the brief? A forever home on a narrow site that maximised daylight with really good connections to a garden, with a study, a studio, a darkroom and a pond & with a nod to mid century architecture. Easy.

What were the key challenges? On just under 7m wide and tapering in half a metre it was a very narrow site. It also had an eclectic heritage overlay and needed parking for one car on site, that along with fitting 2 bedrooms, 2 bathrooms, study, studio, darkroom, kitchen, butlers pantry, laundry, dining, living, substantial outdoor deck, pond, hydronics set up and garden as a real tetris feat! Planning meant the first tricky step was having an onsite carpark but to also have an entry and front facade that wasn’t overwhelmed by a car and driveway.

The second challenge was located the staircase in a way that would appease Rescode (building) regulations as well planning regulations – it needed to be compliant but not seen and to not overlook or overshadow & to fit into strict setback conditions on a very tight site.

Then it was about getting daylight into a site that was filling up quickly and was affectively only one room wide. Next, was sliding a pond running alongside the living room. This may be the narrowest pond made by man but waterlilies have taken to it happily & it has an abundance of water plants & is a lively little pond never the less. The detached studio, darkroom & garden shed bookends the eastern end of the site.

Key products used: Austral Honed Porcelain Blocks. Lysaught Longline Metal Cladding. Ceasarstone Concrete Stone Benchtop Bord Tasmanian Ash Timbers Parthenon Calacutta Marble Laminex Matte laminates Astra Walker Kitchen Mixer Franke Kubus Granite Bowl (sink) Brightgreen Downlights Ink and Spindle Textiles (Living and Bedroom) Dowel Jones bar stools Dowel Jones Sister Lounge armchair Coco Flip Honey Table lamp (Raw ceramic) Coco Flip Puku Ottoman (large & small) Coco Flip Sequence coffee table (Blue) Ghostwares ceramics Oh Hey Grace ceramics Milk Workshop ceramics

What are the sustainability features? It is a passive design house. The living ares were located first to have maximum daylight through the day.

Bathrooms, WIR nook and the laundry are placed south. The outdoor deck has a generous roof & an awning screens the entry and the study from the harsh western sun.

The first floor bedroom, west facing, has an external retractable shade.

Dense, light coloured porcelain blocks make up the ground floor perimeter walls, their mass stabilises internal temperatures as does the cut and polished concrete slab.

An internal light court bring light and fresh area into the middle section of the house; kitchen and dining room. There are high level openable windows to the light court to flush out hot air in summer and a side door to create cross ventilation over the dining area.

A skylight naturally lights the benchtops in the kitchen.

Windows are large to the east and north and kept small and minimal to the south and west, all windows are double glazed.

The stairwell also acts as a small heat stack with operable louvres running floor to ceiling to let hot air out.

There is a concealed multihead a/c unit concealed in lowered ceilings through out the ground and first floor and ceiling fans to cool.

Very thin water tanks run along the southern fence and feed the hydroponic rack which grows herbs and salad greens.

Local timbers line the walls and ceiling and as veneer for joinery fronts.

Adam Cornish Design + Junglefy, Junglefy Breathing Wall

Environmental infrastructure specialists, Junglefy and designer Adam Cornish have collaborated on green wall systems for over five years. Through this collaboration, it became apparent that more could be done to utilise the air cleaning properties of living plants. The Junglefy Breathing Wall is a result of this development: an indoor/outdoor system designed to actively remove pollutants from the air, harnessing nature’s inherent air cleaning and purifying qualities.

The unique insulated chamber mimics a natural microclimate through a series of fins that regulate air and moisture, encouraging the ecosystem to expand and grow new organisms. Unlike traditional potted plants and green walls, the breathing wall system engages the plant, root bundle and soil to filter air in much higher volumes. The modular system is deconstructible, meaning it can be assembled according to the size of the space.

Dale Hardiman + Stephen Royce, Open Garden

Designers Dale Hardiman and Stephen Royce collaborated with technical engineers on their Open Garden project, a conceptual installation created for Melbourne Design Week in 2019. The pair transformed discarded screens into a sculptural mechanism that redistributes electronic waste into a new and functional light source. 

Through a process of bending, fusing and hand-wiring old LCD iPhone screens together, the final connected frame revives these previously discarded materials as a new light form.

Good Citizens, 100% Recycled Eyewear

Inspired by a primary school challenge, a father and son duo repurpose discarded single-use plastic bottles into sunglasses frames, creating two classic styles that are 100% recycled, and made in Sydney. 

Wanting to eliminate any metal components, the pair re-engineered the hinge connecting the arms to the frame so the entire product is completely made from recycled plastic. The resulting clip can be easily removed making pairs of Good Citizens sunglasses colour customisable and easily replaceable. This means if one part breaks, you don’t have to throw out the entire frame. Genius!

Dowel Jones + Soft Serve Studio, New Model

New Model is the environmentally-conscious brainchild of design brand Dowel Jones and industrial design consultancy Soft Serve Studio. The brand was supposed to be launched in March of this year, one week after restrictions were imposed on Victorians. New Model intends to produce zero-waste, carbon-neutral products made from surplus, remnant and waste materials available at a commercial scale.

Eventually aiming to foray into furniture and lighting, the brand’s debut project is the zero-waste 1-Hour Bag which is made from deadstock upholstery materials. Hopefully, New Model launches with a full line of products soon!

Sussex Tapware, Circa range

Sussex Tapware is a true family business. Across four factories, all the company’s production and manufacturing is completed locally. Sussex Taps is one of the only tap companies in Australia to own and operate its own foundry. This enables them to run an internal closed loop system, whereby the chippings and debris leftover from metalwork are melted down and reused in new products.

The Circa range of hardware fittings is handmade by craftspeople locally in Melbourne, and is cast from 100% recycled brass sourced from the company’s own closed loop system. An energy system overhaul in the factories has seen emissions reduce by 30% since the installation of solar panels.

Read our full story on Sussex Taps here.

Five Mile Radius, Waste Terrazzo

Did you know that concrete makes up 8% of the world’s carbon emissions? This innovative concrete surface developed by Five Mile Radius turns that production cycle on its head by creating speckled terrazzo slabs entirely from construction and demolition waste collected around Brisbane. Used as a benchtop, table or seat, each unique piece combines excess wet concrete with crushed demolition waste that’s been directly diverted away from landfill.

All designs are made-to-order and totally customisable, meaning not only are they produced purely by demand, but the customer receives a completely bespoke design. It’s a win-win!

Seed & Sprout, Raise The Bar

One room at a time, Seed & Sprout are devising natural, eco-friendly products alternatives to conventional household items in a mission to make our homes completely (and easily) zero waste. Their latest innovation? A locally-made range of zero waste, waterless personal care products that are free of artificial colourants and synthetic fragrances. 

By replacing water, colourants, palm oil, sulphates, harmful parabens and animal products with essential native oils and natural clays, the Byron Bay-based company has created an effective alternative to these high-use, everyday hygiene products. And amassed a cult Instagram following in the process! The shampoo, conditioner, body bar, shave bar, facial cleanser, exfoliator and hand sanitising soap, which can be purchased in a 100% recyclable aluminium travel tin.

Returnr, Deposit-return system + products

In a bid to reduce the amount of disposable packaging used in transporting meals, Returnr is a hospitality-focussed deposit-return system offers stainless steel reusable food and drink vessels to take-away customers. Simply make a fully refundable $6 deposit, and receive your food or drink in a twin-walled, stainless steel cup, canister or bowl. Stainless steel was chosen for its hygienic properties, and is made from predominantly recycled materials.

As well as significantly lowering the complacent consumption of takeaway packaging, the Returnr model aims to target the human error component of the waste cycle. So, even if you forget the reusable cup you use 99% of the time, Returnr means you don’t have to increase your carbon footprint if you still decide to get a latte.

Koala Eco

Founded in 2017, Koala Eco aimed to create a natural alternative to mainstream domestic cleaning products. By harnessing natural, native ingredients, Koala’s range of cleaning and home products are plant-based and completely non-toxic, relying on the natural antibacterial properties of Australian native flora to replace industry standard chemicals.

All Koala Eco ingredients are plant-derived and biodegradable. The packaging is made from 100% recycled materials, and are completely recyclable themselves. The bottles are designed to be reused, with the company offering a refill option on nearly all their products.

Commune + Co, Cirque du Soil

Accessible, user-friendly compost systems in densely populated urban areas are few and far between. But when you consider that food rotting in landfill produces methane, which is approximately 25 times more potent than regular carbon emissions, the lack of composting infrastructure becomes more of a concern.

This situation is why Commune + Co. developed Cirque du Soil, a community composting initiative that engages local traders and businesses to create a hyperlocal, circular economy for food waste. The subscription-based pick-up service collects organic waste from residents, traders and businesses in local communities and deposits it in a centralised composting system. This regenerates soil, lowers methane emissions and takes urban spaces one step closer to eliminating food waste!

Sustain Australian Food Network, Grow/Source/Eat

Little did we know, but door-to-door delivery services were about to become a LOT more popular in 2020 than anyone suspected. It’s a model Sustain: The Australian Food Network have been trailing for a while with their Grow/Source/Eat project: a weekly delivery service providing subscribers with sustainably sourced and locally grown fruit and veggie boxes from small-scale urban farmers.

The original pilot model was designed to redistribute excess farm products left unsold from weekend farmers markets. This was then expanded to a subscription-based model (fortuitously) in March of this year, to guarantee a more solid customer base, provide consistent revenue and eliminate unnecessary food waste. By partnering with regenerative, next generation farmers the program encourages hyperlocal consumption and education around seasonal produce.

Waverley Mills, 100% Natural Fibre Recycled Range

Waverley Mills was built in 1874, making it Australia’s oldest working textile mill. Alongside the traditional blankets, rugs, throws and scarves it regularly produces, the mill has refined its recycling process with new technologies. Using a completely closed-loop system, this line of natural fibre throws is produced from the mills’ own deadstock materials.

The Design Files + Laminex Design Awards 2020 Sustainable Design or Initiative Award is presented by Country Road.
