What are sinking floors?

Sinking floors can be a sign of subsidence and other issues with a house’s foundations. When it comes to the structural elements of a property, any problems must be investigated as soon as they arise to avoid foundation collapse due to weak areas or voids in the underlying soil.
A building can sink at various points or, in the worst circumstances, the entire foundation could be affected.
With Mainmark’s range of solutions, we work with you to solve the problem of sinking floors, making the remediation process less stressful and helping return your home to a safe and stable condition as quickly as possible.
What does a sinking floor mean?

Concrete floors within a home can sometimes suffer subsidence, which is the sinking of the concrete due to ground movement.
Depending on the location and size of the subsiding area, a building may sink at various localised points, or the movement may spread across the entire footprint of the house’s foundation.
If left untended, subsidence can be a very serious problem that is likely to worsen, creating further areas of sunken floors, wall cracks or other building damage.
What causes sinking floors, and how can Mainmark help?

Sinking floors can often be a sign of subsidence. Some homes are at a greater risk than others when it comes to subsidence. There are also many geological, human-made and seasonal impacts that can make your home more likely to experience a problem.
Mainmark’s ground improvement and concrete floor re-levelling methods for house subsidence are effective for fixing sinking floors in homes of any size.
The Mainmark team of experts will visit your home, assess the damage, and ascertain the cause. Our experienced engineers and technicians establish the underpinning approach needed, creating a plan specific to the needs of your home.
Our cutting-edge solutions are the modern answer to traditional concrete underpinning and are similar to keyhole surgery. Our non-invasive, clean and time-efficient floor fixing solutions are not just for concrete slab floors; we can raise and re-level other types of slabs, strip footings, paths and driveways.
This house lifting and re-levelling method eliminates the need and the cost of ripping out and replacing the floor or demolishing and rebuilding brickwork walls, restoring value to the home. The work is carried out with minimum disruption to the occupants. In many cases, the occupants can remain in the home.
Unlike more traditional methods of underpinning buildings, our resin injection methods are 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.

Teretek® – Resin injection underpinning alternative
Teretek® is an engineered solution for re-levelling subsided buildings that utilises a plural component, expanding polyurethane resin. The expansion force of the material results in the controlled lift of structures, with a by-product of localised bearing capacity improvement through soil densification.

JOG computer-controlled grouting underpinning alternative
JOG computer-controlled grouting uses a multi-point injection technique to insert cementitious grout materials under foundations. It can be used under commercial and residential buildings ranging from single-storey shops to high-rise structures. The injected materials have a controlled set time, which allows for the precise lifting of a structure.
