Foundation and subsidence repairs

Which of these do you need?

Subsidence repairs

Subsidence repair means stopping a building’s foundations from sinking further and then repairing the damage. In most homes the cause, often a leaking drain or a thirsty tree, is dealt with first and the walls are repaired once the ground is stable.

Underpinning

Underpinning is the strengthening of an existing foundation by taking it deeper, or carrying its load down to firmer ground. It is used when the soil under the footings cannot be made stable by removing the cause of movement.

Resin injection ground stabilisation

Resin injection ground stabilisation is a method of strengthening the soil under an existing foundation by injecting an expanding resin through small holes. The resin fills voids and compacts loose ground, and can sometimes lift a settled section back towards level.

Mining subsidence repairs

Mining subsidence is ground movement caused by the collapse or compression of old underground workings, and mining subsidence repair is the work of making the damaged building sound again. For coal-mining damage, claims usually go to the Mining Remediation Authority, formerly the Coal Authority.

Bay window subsidence repairs

Bay window subsidence is movement of a projecting bay, usually downward or outward, independent of the main wall of the house. It is common because many bays were built on shallower footings than the rest of the building.

Extension pulling away repairs

An extension pulling away is differential movement between an extension and the original house, which opens a crack or gap where the two meet. It usually happens because the extension sits on different, often shallower, foundations from the main building.
