What should you know about the ground under Derby?
Derby (DE1, DE22, DE23) has around 270,000 residents and sits in Derbyshire. Nearby, we also cover Belper (7 miles), Ilkeston (8 miles) and Heanor (8 miles).
Clay soils are found in parts of Derbyshire. Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Derbyshire: Brick terraces in former mining towns, gritstone cottages in the Peak, and inter-war and post-war semis.

Site assessment
On site we measure height and lean, check the drainage and the ground at the top and bottom, and look at access for digging out. Walls that support a drive, path or building, or retain more than a modest height, are referred to an engineer.
Written quote
You receive a no-obligation written quote covering demolition, excavation, temporary support, the footing, the new or repaired wall, drainage and spoil removal. It becomes a fixed price in writing once the repair is specified.
Build and drain
The failing section is taken down, the soil supported in short lengths, and the footing cast. The wall is rebuilt with drainage behind it, backfilled with free-draining material, and building control inspects where the work needs it.
Symptoms that point to retaining wall repairs
- Wall leaning forward, or bulging out in the middle of its length
- Bricks or blocks pushed out of line, or coping stones sliding off
- Horizontal or stepped cracks running along the face of the wall

Methods for retaining wall repairs
Rebuilding on new footings
Where the whole wall is failing, it is replaced with a new retaining wall on a properly sized footing, with free-draining backfill, a membrane, weep holes and a drain at the base. Reinforced blockwork faced in brick or stone is common, so the wall matches its surroundings.
Best for: Walls failing along their length, or retaining significant height
Structural repair and partial rebuild
A leaning or bulging section is taken down, the soil behind dug out and supported, and the wall rebuilt on a new footing with drainage and, where specified, reinforcement tied into the sound wall either side. The engineer’s design sets footing size and wall thickness.
Best for: A section that has moved while the rest stays sound
Rules for retaining wall 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 should I budget for retaining wall repairs in Derby?
Guide prices for retaining wall repairs in Derby start from about £490 per wall, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Derby?
We do. Derby and the surrounding area are covered, including nearby Belper and Ilkeston. A free initial assessment from your photos is the first step.
Why do houses in Derbyshire crack?
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. Only an investigation can say why a particular building has moved.
How long does a retaining wall rebuild take?
Drainage and minor repairs usually take a day or two. Rebuilding a garden retaining wall on new footings typically takes one to three weeks, depending on its length, height, access for digging and any wait for the engineer’s design or inspections.
Do I need an engineer for a retaining wall?
For low walls holding back a planting bed, often not. Walls retaining more than a modest height, often taken as more than about a metre, or supporting a drive, path, building or neighbour’s land, generally need an engineer’s design. An independent chartered structural engineer is appointed where needed, and we can arrange this.
