What should you know about the ground under Derbyshire?

Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Derbyshire, most homes are brick terraces in former mining towns, gritstone cottages in the Peak, and inter-war and post-war semis.

Symptoms that point to mining subsidence repairs

The whole house leaning slightly, with doors swinging open
A dip, hollow or hole opening in the garden or drive
Cracks running through the foundations and up both faces of a wall
Steps or ridges forming in paths, kerbs or garden walls

Methods for mining subsidence repairs

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

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

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

From first photo to finished repair

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.
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.
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.

Do you need approval 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.

Frequently asked questions

Is the ground in Derbyshire prone to subsidence?

East Derbyshire, including Chesterfield, Ilkeston and Heanor, lies on the Coal Measures with a long history of shallow and deep coal mining. The Peak District to the west is limestone and gritstone, and Derby itself sits largely on Mercia Mudstone. Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will mining subsidence repairs cost in Derbyshire?

On East Midlands rates, mining subsidence repairs starts from about £80 per metre of crack, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.

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.
