Which repair method suits a home in Cwmbran?
Crack stitching and making good
Where the ground has stopped moving and the damage is cracking, the walls are stitched with stainless helical bars, repointed and replastered. This covers a large share of mining damage, especially legacy movement that settled years ago and left cracks behind.
Best for: Cracking after movement that has now stopped
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
What happens when we carry out mining subsidence repairs in Cwmbran?
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.
Written price to the scope
We price the repair from the engineer’s or claim schedule and confirm a fixed price in writing once the work is specified. Where a claim body or insurer is handling the repair, their own process for appointing contractors applies.
Repairs and records
Work proceeds once any ground treatment is complete and the engineer is satisfied. We stitch, stabilise or underpin as specified, make good inside and out, deal with building control where needed, and hand over records for your file.
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.
Mining subsidence repairs in Cwmbran: questions and answers
How much should I budget for mining subsidence repairs in Cwmbran?
Guide prices for mining subsidence repairs in Cwmbran 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 Cwmbran?
Yes, Cwmbran is covered, along with postcode districts NP44. We also cover nearby Pontypool and Risca.
Why do houses in Gwent crack?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.
How do I make a mining subsidence claim?
Start by reporting the damage to the Mining Remediation Authority, describing when it appeared and including photographs. They will usually arrange an inspection and investigation. Report promptly, because time limits can apply. Keep copies of everything you send, and notify your home insurer in parallel.
Can you repair mining damage that is not part of a claim?
Yes. If the damage is old and settled, or a claim has been closed, we can repair it privately. Send photos for a free initial assessment and you will receive a no-obligation written quote. If the cause is unclear, an engineer’s inspection first is sensible.
