What are sinking floors?
Sinking floors can be a sign of subsidence and issues with house foundations. When it comes to the main structural aspects of a property, it is essential they are looked at as soon as a problem arises – to avoid foundation collapses from weak voids.
A building can sink at various points or in the worst circumstances can affect the entire foundation.
With Mainmark’s range of effective solutions, we can work with you to make the whole process less stressful allowing you to live happily in your home again.
What does a sinking floor mean?
Concrete floors within a home can sometimes suffer subsidence, which is the sinking of the concrete due to movement of foundation ground.
A building can sink at various localised points or can be spread across the entire footprint of the house foundation, depending on where, and the size of the affected area.
Subsidence, if left untended can be a very serious problem, which is likely to worsen, creating further sinking floors, wall cracks or other significant building damage.
How can we help
What is the cause of sinking floors and how can Mainmark help ?
Sinking floors can often be a sign of subsidecne. Some homes are at a greater risk than others when it comes to subsidence. There are also many geological, man-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 likened to keyhole surgery. Our non-invasive, clean and time-efficient floor fixing solutions are not just for concrete slab floors; we can raise and relevel strip footings, a range of slabs and we can re-level paths and driveways too.
This house lifting, and re-levelling 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 the minimum of disruption to the occupant. In many cases the occupant can remain in the home.
As opposed to more traditional methods of underpinning buildings, our resin injection methods are 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.

Soil stabilisation FAQ’s
What happens with unlevel driveways, floors and hardstand areas?
After the application of the Mainmark solution, unlevel surfaces will become aligned again as the ground underneath is strengthened and re-supported. Simple cosmetic repairs may be required.
Will there be a mess?
Very little, if any. We use Teretek® engineered Resin Injection technology, which is likened to “keyhole surgery”, or JOG Computer-Controlled Grouting, with no major excavation and minimal disruption or mess. The injection holes required are very small.
How long does it take?
Each project is different and depends on the required amount of lift, area for correction, building construction, and ground conditions. Most projects can be completed in a day or two, and we can work at night or on one area at a time, so your business can keep operating.
Do i need to send my workers home?
No, most projects don’t require you to vacate the premises or even move furniture or equipment. For the most part, you can keep operating as normal. Driveways can often be driven on in as little as 30 minutes after treatment.
What warranty will i get?
The materials we use have been developed for use underground and have been specifically engineered to resist shrinkage and deterioration. Teretek® is warranted by Mainmark for an industry-leading period of 50 years.
Is it safe and environmentally friendly?
Injected Teretek® and JOG materials are environmentally inert and have no detrimental effects on the environment.
