Underpinning contractors

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.

Underpinning contractors FAQ’s
Do I need a structural engineer for underpinning?

It is highly recommended to involve a structural engineer if you suspect your property is suffering from  subsidence and you are considering underpinning or other solutions to address it.

Mainmark works in conjunction with structural engineers to ensure that their subsidence correction solutions, like Teretek® geopolymer injection technology, are applied effectively and safely, adhering to the appropriate standards and regulations.

Should underpinning be carried out every 40 years?

Correctly executed subsidence correction treatment such as underpinning should last the lifespan of a building. However, various factors, including the type of soil, the quality of original construction, and environmental conditions may mean that additional work could be required in the future . Mainmark’s solutions, such as geopolymer resin injection, aim to provide long-lasting stabilisation, potentially reducing the need for future underpinning. Their methods are designed to adapt to different soil types and conditions, offering a more permanent solution to foundation issues.

What are the alternatives to underpinning?

Among modern alternatives to underpinning are geopolymer resin injection and cementitious grouting. These methods are less disruptive and often more cost-effective than traditional underpinning methods, providing a viable solution for various foundation issues without the need for extensive excavation or structural alterations. Mainmark offers both Teretek® resin injection technology and JOG Computer-Controlled Grouting
