Multiple Crack Repair Methods Used to Repair Period Cottage

This beautiful cottage in Berkshire is believed to have been built around 1730 and has a number of old and more recent additions.

The property was suffering from external and internal cracking throughout. Much of the cracking had been caused by differential movement. This occurs when different sections of the building, in this case, later additions, are built on separate foundations. There can be a difference between the rate and the amount that the foundations settle, which causes separation and cracking between the walls. The cottage was also suffering from brick arch lintel failure, which caused extensive internal and external cracking between the windows of the ground and first floor, both to the front and rear.

Following a site survey, our engineer designed a repair specification comprising of masonry beaming, multiple crack repair methods, and pinning.

Johnson & Johnson Vision Care Centre -

Commercial Structural Repair Services Projects

The Challenge

ASRS were consulted to carry out a wall tie investigation to a large commercial property that had no obvious signs of movement other than one panel of masonry had leaned outwards 80mm at the top of the panel. After an extensive survey it was discovered the inner and outer leafs did not have sufficient wall ties to connect the two skins of masonry.

The Solution

ASRS carried out numerous tests and endoscope surveys to assess the existing ties. Pull out tests were carried out on various remedial wall ties and the Helifix resi-tie achieved the best pull out results achieving pull out ratings at over 2.5KN’s. The masonry was drilled only requiring a 12mm hole and the tie installed using portable drills and then resin fixed on the outer leaf.

Concrete Repairs to Local Primary School

The Problem

A local primary school close to our head office contacted ASRS to provide a specification and repair method to the concrete surrounds to a block of classrooms. Our surveyor met the local council on site and performed a hammer test to identify the worst areas of oxidisation.

The Solution

The repair scheme for this project was specified due to the oxidisation of the steelwork resulting in the concrete spalling and falling off making it dangerous for the pupils if the repairs were not to take place.

ASRS specified hacking off the loose and spalling concrete, cleaning the exposed steelwork and apply a zincrich primer to stop corrosion and then apply a high strength concrete repair mortar.

Experience the High Grade Helifix Repair Services from ASRS Ltd 

Cracks in walls, around windows and doors, stepped cracks in brickwork, and other structural issues can occur for various reasons and often cause concern for property owners or tenants.

Cracks in masonry are commonly caused by factors like ground movement, subsidence, heave, environmental conditions (such as freeze/thaw cycles), increased loads or stress, replacement of doors or windows, drain failures, and the addition or removal of large vegetation. ASRS Ltd are helifix crack repair specialists, expertly diagnosing the cause of these cracks and designing effective solutions.

As certified installers of Helifix Masonry Repair Systems, we provide Helifix insurance-backed guarantees for most projects. Additionally, we offer expert advice, free site visits, and tailored structural programs. When masonry has cracked or failed, the Helifix Helibeam System offers horizontal bed-joint reinforcement, eliminating the need for demolition and rebuilding. This system utilizes high-tensile stainless steel helical bars combined with cementitious, thixotropic grout to securely bond the bars to the masonry.

Bed joint reinforcement, also known as masonry beaming, ties the masonry together to form deep beams that help redistribute structural loads. Additional helical ties and fixings can be added as needed for crack stitching and to provide lateral and vertical restraint, completing the system. This approach is suitable for all masonry types, including brick, block, and stone structures. The Helibeam System provides a structurally sound, cost-effective alternative to underpinning and other traditional repair methods, with much less disruption and stress. It minimizes impact on the ground, building, and occupants, and after repointing and finishing, the building remains virtually unmarked. 

ASRS Ltd is an approved installer of the Helibeam System, providing cost-effective, non-intrusive, and discreet solutions for all aspects of remedial masonry stabilization. We have received amazing reviews from all our valued customers who only choose us.  Don't wait, connect with our experts today to enjoy the great benefits of our services.

Choose the Best Lateral Restraint - Bowed Walls Structural Repair Services

ASRS Ltd uses lateral restraint wall ties to connect masonry to floor or ceiling joists, effectively securing both together. The process involves drilling a hole in the masonry, aligned with the timber joists. The leading edge of the restraint tie, shaped like a drill bit, cuts into two or more joists as it is installed. The masonry end is then fixed with resin, creating a solid bond. Finally, the hole is filled with a colour-matched mortar to achieve an invisible finish.

Additional repair methods, such as crack stitching and bed joint reinforcement, may be needed to address cracks or reinforce the masonry. Bowed walls and outward movement are often due to weak construction and insufficient connection between the masonry and joists. This lack of lateral support is a common problem in older buildings, often seen in the form of bowing or bulging walls.

End-of-terrace gable and side walls also commonly lack lateral restraint when floor and ceiling joists run parallel to the masonry without any physical connection, leading to outward movement and cracking, especially under increased structural loads. We offer free site assessments in Bristol for both residential and commercial clients to evaluate the issue and recommend a suitable repair plan tailored to the project’s requirements. ASRS is an approved installer of the Helibeam System, providing cost-effective, non-invasive, and discreet solutions for masonry stabilisation.

Our skilled installation teams are highly trained in all masonry repair processes, meeting the highest standards of health and safety. Most of our design and installation specifications come with a 10-year indemnified guarantee on Helifix repairs and micro piling, along with a 25-year guarantee for wall tie replacements. Contact us now to get insights into our exemplary lateral restraint-bowed walls structural repair services. We are proud to receive amazing reviews and feedback from all our valued clients.
