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

One of Mainmark’s experts will visit the site to conduct a survey, assess the damage and ascertain the cause. Our experienced engineers and technicians are skilled at establishing the most appropriate methods and creating treatment plans specific to the needs of each 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 structures can all 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’s non-invasive underpinning solutions can lift foundations and re-level buildings By injecting our structural resin or cementitious grout mix into the ground under the building’s footings, we can stabilise the ground under the foundations and lift the structure back to level. In most cases, this closes any cracks in the walls 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. 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 cement grout under a property at as many as 128 points to create a simultaneous, precise re-levelling process.
