Seal It Right from the Start: Why ADT Mix LW+ Is India’s Smartest Integral Waterproofing Solution

The Science of Waterproofing: Why Concrete Fails

While concrete appears to be a solid and durable material, a closer examination under a microscope reveals a complex internal structure filled with numerous pores and micro-capillaries. These tiny channels, which often go unnoticed, play a significant role in the material's behaviour. They enable the infiltration of water, salts, and various aggressive chemicals, which can gradually permeate the concrete. As these substances seep in, they initiate a series of chemical reactions and physical processes that can compromise the integrity and strength of the structure over time. This breakdown can lead to issues such as cracking, spalling, and overall deterioration, emphasising the importance of understanding and addressing the vulnerabilities of concrete in construction and maintenance.

Common Damage Due to Moisture Ingress:

Steel Reinforcement Corrosion – rusting weakens the core

Efflorescence – white salt deposits on plaster

Cracking – due to drying shrinkage and water movement

Seepage in bathrooms, balconies, and tanks

Fungal and algae growth – leading to unhealthy interiors

📊 Fact: More than 70% of water-related concrete failures in India are traced to insufficient internal waterproofing, as per IS 2645:2003 studies.

Traditional Waterproofing vs. Integral Waterproofing

🔧 Traditional Methods:

Surface coatings, membranes, and post-construction treatments are essential components in construction and maintenance projects aimed at enhancing durability and protection. Surface coatings, which can include paint, sealants, and protective films, provide a barrier that helps resist moisture, chemicals, and abrasion. Membranes, often made from materials like rubber or thermoplastic, are specifically designed to offer waterproofing and prevent water infiltration in various structures, such as roofs and basements. Post-construction treatments, which encompass applications like waterproofing agents and curing compounds, work on surfaces after the initial construction is completed to further safeguard against wear and environmental damage.

While these solutions are incredibly useful for improving the longevity and performance of buildings, they tend to be reactive rather than proactive. Over time, exposure to environmental elements, wear and tear, and chemical interactions can lead to the degradation of these materials, potentially compromising their effectiveness and necessitating maintenance or replacement.

Limitation

Traditional Methods

Requires surface preparation

Yes

Prone to wear and weather

UV, heat, and abrasion damage

Risk of incomplete coverage

High – especially around edges, joints

Maintenance cycle

Re-application every 3–5 years

Internal protection

❌ Not provided

Integral Waterproofing:

This innovative technology safeguards concrete from the inside out during the mixing process. By working at the molecular level, it effectively prevents water from penetrating the material, guaranteeing a lasting waterproof solution. This means that the concrete not only remains resilient against water damage but also enhances its overall durability, making it suitable for various applications where moisture resistance is crucial.

What Is ADT Mix LW+? Understanding the Product

ADT Mix LW+ is a liquid integral waterproofing compound developed by ADT Industries, engineered to meet Indian site conditions and IS 2645:2003 guidelines.

It works by modifying the internal structure of the concrete matrix, reducing porosity and increasing durability, even in extreme environments.

Key Properties:

Liquid Formulation – easy to mix, no clumping

IS 2645:2003 Certified

Chloride-Free – safe for reinforcement

Non-toxic and Eco-friendly

Compatible with OPC, PPC, and blended cements

How ADT Mix LW+ Works: The Internal Shield Mechanism

Once mixed into concrete or mortar, ADT Mix LW+ reacts chemically with calcium hydroxide released during cement hydration. This reaction:

Fills capillaries and micro-cracks

Forms a hydrophobic (water-repelling) barrier

Enhances the density and cohesion of the mix

Prevents future ingress of water, salt, and harmful chemicals

This mechanism turns the entire volume of concrete into a self-protecting, water-resistant material.

Technical Features and Performance Benefits

Feature

Description & Advantage

Liquid Form

Easy dosing, faster mixing, no manual lump breaking

Capillary Blocking

Form crystals that block water paths permanently

Shrinkage Control

Minimizes cracks due to shrinkage or bleeding

Water Reduction

Improves workability and reduces water demand by up to 15%

No Setting Time Delay

Does not interfere with cement hydration

Enhanced Durability

Ideal for coastal, humid, and chemically aggressive conditions

Improves Compressive Strength

Denser structure leads to longer life

🔍 Use of ADT Mix LW+ results in more compact concrete with fewer voids — improving both structural performance and waterproofing in one step.

Dosage Guidelines and Application Process

Recommended Dosage:

100 ml to 250 ml per 50 kg of cement (0.2%–0.5% by weight)

Mixing Process:

Pre-measure the required quantity of ADT Mix LW+.

Add it to the first portion of gauging water.

Mix thoroughly into the concrete/mortar.

Add the remaining water and mix until uniform.

Apply and cure as per standard practice.

Important:

Do not overdose; this may slightly delay setting time.

Ensure proper mixing for full dispersion.

Where to Use ADT Mix LW+

Ideal for:

RCC Roof Slabs and Screeds

Bathrooms and Wet Areas

Plastering (internal and external)

Basements and Retaining Walls

Overhead Water Tanks and Sumps

Balconies, Podiums, Swimming Pools

Tunnels, Dams, and Drainage Structures

Case Examples and Industry Use

Residential Projects:

Reduced seepage complaints in RCC roof slabs during monsoon in Maharashtra housing projects.

Infrastructure Projects:

Used in the waterproofing of underground water tanks and sumps in Kerala, eliminating algae and internal leaks.

Commercial Projects:

Plaster treated with LW+ in hospitals and schools showed no efflorescence or paint failures after 2+ years.
