How much will repairing subsidence cost?

It can be a worrying time when you discover subsidence in your home, and one of your primary concerns will be how much subsidence costs to fix.
Depending on the severity of the problem and the specifics of your property, subsidence costs can vary greatly, and Mainmark’s modern techniques may help you save thousands of pounds.
Three common techniques for dealing with subsidence in residential homes are underpinning, piling and resin injection technology. As a rough guide, these three measures for treating subsidence in an average three-bedroom home can cost*:
£23,000 for piling
£13,000 for mass concrete
£7,500 for Mainmark’s resin injection
*Average costs are based on October 2023 prices and are for comparable like-for-like results.

Other expenses may also need to be factored into your calculations, especially if you opt for one of the more disruptive traditional piling or mass concrete underpinning methods. For example:
Surveys, inspections and building control applications
Party wall agreements if you live in an attached or semi-detached property
Alternate accommodation for your family during the works
Hard and soft landscaping around your home after the underpinning or piling is complete
Disruption to your daily family life
With Mainmark’s advanced subsidence treatment and ground improvement methods, many of these costs can be mitigated or avoided entirely, helping you to save money.
Why do subsidence costs vary so much?

Traditionally, the only solution for subsidence in residential properties was underpinning, using techniques such as mass concrete or piling. These involve digging out from under the foundations of your home, an expensive, complicated and time-consuming process that is disruptive to your home, family and probably your neighbours.
Mainmark’s methods, on the other hand, keep subsidence costs down because they are quick to implement and require none of the extensive digging under your home.
Our Teretek® resin injection technique is similar to keyhole surgery. We drill small holes, approximately 16mm in diameter, through the floor or under your home’s foundations and then inject our specially formulated resin into the soil underneath, often to various depths. Our award-winning JOG computer-controlled grouting technology can also be used to treat subsidence quickly and effectively. Mainmark ground improvement technologies:
Support foundations by filling in any voids under your home
Can gently lift your property, bringing it back to level
Improves the soil underneath your house, increasing ground load-bearing capacity and mitigating liquefaction.
Once the work is completed, only minor repairs may be necessary, such as filling in the small holes drilled through your floors and patching up the cracks in the walls that were caused by the subsidence.
Mainmark’s methods typically take less than a full day, keeping subsidence costs – and stress – to a minimum.

Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.

Teretek® – Redcing subsidence cost with resin injection
Teretek® is an engineered solution for ground improvement and re-levelling of subsided residential homes, using a plural component, expanding polyurethane resin. Teretek® helps in reducing the cost of subsidence by working in a similar way to keyhole surgery. Small holes are drilled under the foundations in order for Mainmark’s proprietary, environmentally inert resin to be injected under the house foundations, improving the stability of the ground and re-levelling the home.

Reducing subsidence cost with JOG computer-controlled grouting
JOG computer-controlled grouting uses a multi-point injection technique. This technology typically uses cementitious grout to re-level structures, including residential homes. This means that the subsidence cost need not be high as the cementitious grout is injected under the foundations of your home, using computers to accurately control the injection amounts in the various predetermined locations.
