Mining subsidence repairs in Newport
Whether old mine workings lie beneath Newport is a question for the mining records, not for guesswork. A coal mining report shows recorded seams, shafts and past workings nearby, while an engineer’s inspection is what links any damage to them.

Repair options we may recommend
Ground stabilisation by resin injection
For localised settlement in the upper soil layers, expanding resin can be injected beneath the footings to firm the ground and sometimes reduce a small tilt. It is not suitable for large voids deep below, which need grouting or other specialist treatment first.
Best for: Shallow settlement once deeper voids are ruled out or treated
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
What to expect when we carry out mining subsidence repairs
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.
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.
Your mining subsidence repairs questions
How much will mining subsidence repairs cost in Newport?
Guide prices for mining subsidence repairs in Newport 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.
Do you cover Newport?
Yes, Newport is covered, along with postcode districts NP10, NP19, NP20. We also cover nearby Risca and Cwmbran.
Is the ground in Gwent prone to subsidence?
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.
What about salt, lead or ironstone mining?
Damage from non-coal mining follows different routes. Cheshire’s brine areas have their own statutory compensation arrangements, while metal, ironstone and limestone workings often have no equivalent scheme, leaving your home insurer as the main route. A solicitor or your insurer can confirm which applies.
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.
