  • Cracks in internal or external walls

  • Cracks around doors and windows

  • Doors and windows sticking unexpectedly

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.

Non-invasive subsidence repair…

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.

Trusted by homeowners, insurers and property professionals across the UK modern subsidence solutions address the cause of foundation movement without the disruption of traditional underpinning.

Our 4 step approach to subsidence repair…

Step 1. Assess

Our subsidence specialists visit the property to do a technical inspection of the the walls and floor.

Step 2. Investigate

Ground conditions and structural symptoms are evaluated to determine the most appropriate solution.

Step 3. Treat

If a resin solution is suggested is it injected through small holes to improve the ground beneath the structure.

Step 4. Monitor

Works are verified and documented to ensure the required outcomes have been achieved.

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.
