Methods for mining subsidence repairs

Pricing an engineer’s repair scope

When a claim is under way, the engineer or claim handler usually writes the scope of repairs. We price that schedule item by item, at no charge to request, and carry out the work if you choose us. Anything outside the scope is shown separately.

Best for: Homeowners with a mining claim or engineer’s report in hand

Underpinning to sound ground

Where the engineer specifies it, foundations are taken down by mass concrete, beam-and-base or mini-piles to ground that will not move further. On mining sites the design often follows grouting of old workings so the new foundation sits above a stable mass.

Best for: Ongoing movement or damage beyond what crack repairs can hold

Report and photograph
Photograph every crack with a scale and note the date it appeared. Report suspected coal-mining damage to the Mining Remediation Authority, or the operator of a working mine, and notify your home insurer. Time limits can apply, so report promptly.
Check the mining record
A coal mining report or a search of mining records shows whether recorded workings or shafts lie near the property. Records are incomplete, so a clear report does not rule mining out, and a recorded seam nearby does not prove it is the cause.
Engineer’s assessment
An independent chartered structural engineer inspects the damage and, if needed, recommends drilling or ground investigation to locate voids. We can arrange the engineer. Their report sets out the cause, whether movement has stopped and what repair is needed.

Rules for mining subsidence repairs in Wales

In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.

Frequently asked questions

How much should I budget for mining subsidence repairs in Bridgend?

Guide prices for mining subsidence repairs in Bridgend start from about £75 per metre of crack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Can you survey a property in Bridgend?

Yes, Bridgend is covered, along with postcode districts CF31, CF35. We also cover nearby Porthcawl and Llantwit Major.

Why do houses in Mid Glamorgan crack?

Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys. Only an investigation can say why a particular building has moved.

Can mining subsidence start again years later?

It can, particularly over shallow workings or old shafts, where collapse can happen long after mining ended. Movement from deep longwall mining generally settled within a few years of extraction. An engineer can judge whether current damage is old, settled cracking or new movement.

Is my house affected by mining because it is on a coalfield?

Not necessarily. Many homes on coalfields have no mining-related damage at all, and cracks there can still come from clay, trees or drains. A coal mining report shows recorded workings nearby, and an engineer’s inspection is needed to link damage to mining.
