Typical buildings in Nottinghamshire: Brick terraces in former colliery towns, Victorian villas in Nottingham, and inter-war and post-war semis.

How we usually approach mining subsidence repairs

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

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 during mining subsidence repairs, step by step?

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 England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Is the ground in Nottinghamshire prone to subsidence?

West Nottinghamshire around Mansfield, Hucknall and Kirkby-in-Ashfield is on the Coal Measures with a long mining history, while Nottingham sits on sandstone with Mercia Mudstone clay to the south and east. Only an investigation can say why a particular building has moved.

What should I do if a hole opens in my garden?

Keep everyone away from it and do not try to fill it yourself. Report it straight away to the Mining Remediation Authority if coal mining may be involved, or to your council and insurer otherwise. Old shafts can be deeper and wider than the visible hole suggests.

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.
