Underpinning contractors for subsidence solutions

When subsidence is found or suspected at a property, it’s essential to enlist the help of experts as soon as possible. Underpinning contractors and other subsidence solution providers can help to diagnose the problem and advise on how to treat the problem effectively.
Mainmark offers fast and non-invasive technologies for dealing with the causes of subsidence. While traditional underpinning contractors use complicated and disruptive processes of digging under the property’s foundations to insert piling or mass concrete and other fillers in order to improve the existing foundations. Our approach is quick as well as significantly less disruptive and aims at improving the ground under the foundations.
With our Teretek® resin injection technology, small 16mm holes are drilled under the foundations of the property or through the floor slab if needed. Then resin is injected into precise locations. Our JOG computer-controlled grouting method is another non-disruptive alternative to traditional underpinning. Acting as alternatives our solutions:
Improve the soil – Increasing the ground’s load-bearing capacity and mitigating liquefaction
Lift and re-level the building – Gently returning the structure to its correct alignment
Fill in voids in the ground – Supporting the foundation and enhancing its structural integrity.
Our targeted approach effectively resolves the underlying causes of subsidence in commercial buildings and residential homes, restoring your investment and ensuring the long-term stability and safety of the structure. They can also be utilised in road and rail networks, industrial plant, airport railways or harbour and sea walls.
Alternatives to traditional underpinning contractors

If you’re considering contacting traditional underpinning contractors for subsidence solutions, Mainmark’s methods offer a different approach to treating subsidence – an option that may prove more suitable for your requirements.
As opposed to underpinning contractors, our specialists use surgical-like precision. We drill small holes under the foundation of the building and through concrete floor slabs and then precisely inject inert materials at key locations. This targeted approach resolves the causes of subsidence usually in one or two days, rather than the weeks or months that traditional underpinning contractors would require. Our process is:
Fast – Returning the structure to a safe and solid state as quickly as possible.
Dependable – The injected materials are environmentally inert and provide a long-term solution for subsidence.
Non-disruptive – There’s no need for people to vacate the building, or contents to be removed, and once work is completed, surfaces are immediately trafficable.
Cost-effective – The treatments cost less than underpinning contractors would charge, and there are fewer associated costs.

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.
