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 can suffer subsidence, which is the concrete slab sinks due to ground movement beneath a home.
This can be due to:
Changes in the soil moisture levels because of the climate, which can cause the ground to shrink or swell. This can be a particular problem in the clay-rich soils found in areas like Dublin, Meath and Cork
The roots of nearby mature trees, which can have a similar impact because these suck moisture from the ground, again causing it to shrink
Heavy traffic local to a property can cause sub-surface vibrations which can result in subsidence
Leaking drains which wash away soil particles, particularly in sandy soils, can destabilise foundations
Historical land use such as mining or peatland drainage in rural areas can lead to ground settlement
Any subsidence problem should be investigated as soon as it arises so that weak areas or voids in the underlying soil can be addressed.
Subsidence can cause a building's floor to sink, or, in the worst circumstances, it can affect the foundations of the entire house. Whatever the extent of the damage, subsidence can be a very serious problem, one that is only likely to get worse if left unattended.
How can Mainmark help?

One of Mainmark's experts will visit your home to investigate what is causing the floor slab to sink. Based on their investigations, they will suggest the most appropriate remediation solution specific to the needs of your home.
Mainmark can install a variety of subsidence solutions including resin and grout injection as a swift, non-invasive and cost-effective alternative to traditional piling. Our Teretek® resin injection and JOG computer-controlled grouting techniques have been specially developed to deliver material into the ground beneath the floor and foundations to:
Fill any voids;
Improve the load-bearing capacity of the ground; and
Lift and re-level the floor
Unlike more traditional underpinning methods, Mainmark's resin and grout injection solutions are quicker and less disruptive. In most cases, the injection is carried out from the outside your home using 16mm diameter tubes. If interior injection is required to treat a floor, a smaller 6mm diameter tube is used to minimise any damage to your home.

Teretek® – resin injection for treatment of sinking concrete floor slabs
Teretek® is an engineered solution for re-levelling subsided residential homes and treat sinking concrete floor slabs. Teretek® can be described as keyhole surgery for homes. Small holes are drilled under (or sometimes through) the floor slab to enable injection tubes to be inserted. These tubes enable Mainmark’s proprietary, environmentally inert resin to be injected at strategic points beneath the slab. The resin fills any voids and improves the stability of the ground. It can also be used to lift and re-level the floor, sometimes known as slab-jacking.

JOG computer-controlled grouting for treatment of bay window subsidence
JOG computer-controlled grouting is a multi-point injection technique. This technology uses cementitious grout injected into the ground to stabilise it and to re-level structures. It can be used to effectively treat concrete floor subsidence by injecting cementitious grout beneath the floor slab using computers to accurately control injection amounts in predetermined locations.

Sinking floor FAQs
What happens to sunken floors after treatment?
After the application of the Mainmark solution, sunken floors will become raised and re-aligned as the ground underneath is strengthened and re-supported. Simple cosmetic repairs may be required.
