Mining subsidence repairs in Gillingham
Whether old mine workings lie beneath Gillingham 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.

Why does the ground in Kent matter for mining subsidence repairs?

Kent is one of the parts of the UK where clay soils are most likely to move with the seasons. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.

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
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
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 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.
Your mining subsidence repairs questions
How much will mining subsidence repairs cost in Gillingham?
Guide prices for mining subsidence repairs in Gillingham start from about £90 per metre of crack, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Gillingham?
Yes, Gillingham is covered, along with postcode districts ME7, ME8. We also cover nearby Strood and Gravesend.
Is the ground in Kent prone to subsidence?
North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. 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.
Who pays for coal-mining subsidence damage?
Liability for damage from past coal mining usually rests with the Mining Remediation Authority, or with the operator of a working mine. They investigate whether coal mining caused the damage before agreeing any repair. Tell your home insurer as well, because policy cover and the mining claim can overlap.
