Mainmark’s subsidence and ground improvement treatment methods effective for fixing cracks in walls in homes and buildings of any size.

The Mainmark team of experts will visit the site to conduct a survey, assess the damage, and ascertain the cause. Our experienced engineers and technicians establish the most approproate method and create a treatment plan specific to the needs of the building

Houses and buildings that develop cracks in walls, which can occur internally and externally, often need to be re-levelled. These structures require their foundations to be lifted. As the building is re-levelled wall cracks generally close, leaving only a little cosmetic crack repair, such as patching and painting, to deal with. Most importantly, structural damage is resolved, to the relief of the building owner.

Individual houses, terraced houses, apartment buildings and commercial strcutures alike can suffer from settlement. Settlement of a floor slab or foundations, supporting the walls or structure of the building, often causes cracking in the brickwork walls.

Mainmark complete foundation and building lifting by using our non-invasive underpinning solutions. By injecting one of our structural resins into the ground under the building’s footings for foundation repair, we can stabilise the ground under foundations and lift the structure back to level, normally closing any cracks in internal walls of house that may have formed.

As opposed to more traditional methods of underpinning buildings, our Teretek resin injection solution is quicker and in most cases done from the outside using 16mm diameter tubes and if interior injection is required, only a 6mm tube is used. The size of the tubes means that there is minimal intrusion into the property.

Another of our non-invasive crack repair methods is JOG Computer–Controlled Grouting which allows our team to inject a property with a cement grout at as many as 128 points to make create a simultaneous, precise re-levelling proces
