What should you know about the ground under Gravesend?

Postcode districts DA11, DA12 cover Gravesend, a Kent town of about 54,000 people. Nearby places we cover include Swanscombe (3 miles), Longfield (4 miles) and Strood (6 miles).

Much of Kent sits on clay that shrinks in dry summers and swells in wet winters. 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.

Which repair method suits a home in Gravesend?

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

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

What happens when we carry out mining subsidence repairs in Gravesend?

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.
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.
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.

Mining subsidence repairs in Gravesend: questions and answers

What is the price of mining subsidence repairs in Gravesend?

Guide prices for mining subsidence repairs in Gravesend 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 carry out mining subsidence repairs in Gravesend?

We do. Gravesend and the surrounding area are covered, including nearby Swanscombe and Longfield. A free initial assessment from your photos is the first step.

Does the ground around Gravesend cause cracking?

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.

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.
