How we usually approach mining subsidence repairs

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

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 during mining subsidence repairs, step by step?

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.

Why do houses in County Durham crack?

Much of County Durham sits on the Durham Coalfield, worked for centuries, often under a cover of glacial clay. Many former pit villages have recorded mine workings, and coal mining searches are standard for property here. Only an investigation can say why a particular building has moved.

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.

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.
