Repair subsidence without major excavation
For decades, traditional underpinning was considered the standard solution for subsidence.
Today, many UK properties can be repaired using alternative solutions like resin injection which strengthens the ground beneath foundations, or load bearing steel screw piles, rather than extensive excavation associated with traditional underpinning.

At Mainmark we provide fast, non-invasive subsidence repair solutions that are effective and non disruptive taking days rather weeks and with no need to relocate during works.

Settlement vs Subsidence: What's the Difference?
Many property owners use the terms interchangeably, but they are different issues.
Settlement is the natural compression of ground beneath a building after construction. It is often gradual and may not indicate a serious structural issue. Typical signs include:
Small hairline cracks
Minor cosmetic movement
Slight unevenness
Subsidence occurs when the ground beneath a property moves downward, reducing support to foundations and causing structural movement. Typical signs include:
Larger cracks in walls
Sticking windows and doors
Sloping floors
Structural movement
A professional assessment can help determine which issue is affecting your property.

Frequently Asked Questions
How do you repair subsidence in a house?
Subsidence repair starts by identifying why the ground beneath the foundations is moving. The cause may involve shrinkable clay, leaking drains, poorly compacted ground, nearby trees or weak soils. Once the cause is understood, the ground and foundations can be re-supported using an appropriate engineered solution, such as resin injection, grouting or, where necessary, traditional underpinning. Re-levelling may also be possible where the structure has dropped.
