Is Kent prone to ground movement?

Sittingbourne (ME9, ME10, ME12) has around 54,000 residents and sits in Kent. We also take enquiries from nearby Faversham (7 miles), Gillingham (9 miles) and Maidstone (11 miles).

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.

Methods for 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

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

From first photo to finished repair

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.

Frequently asked questions

How much will mining subsidence repairs cost in Sittingbourne?

Guide prices for mining subsidence repairs in Sittingbourne 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.

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.

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.

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.
