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

Temporary support and reducing load

While a repair is designed and programmed, a dangerous wall may be propped, or soil and loads near the top removed to reduce the push. Moving parked cars or a shed back from the wall is sometimes the simplest first step.

Best for: Walls that are moving now and need making safe

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.
Engineer’s design
Where the wall needs it, an independent chartered structural engineer is appointed to design the repair or new wall, including footing, thickness, reinforcement and drainage. We can arrange this, and the design forms the basis of the quote.
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

Ground cracking or sinking along the top of the wall
Water seeping through joints, or white salt staining, after rain
Bricks or blocks pushed out of line, or coping stones sliding off

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

What is the price of retaining wall repairs in Falmouth?

Guide prices for retaining wall repairs in Falmouth start from about £515 per wall, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you carry out retaining wall repairs in Falmouth?

Yes, Falmouth is covered, along with postcode districts TR11. We also cover nearby Truro and Redruth.

Does the ground around Falmouth cause cracking?

Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. Only an investigation can say why a particular building has moved.

Is a leaning retaining wall dangerous?

It can be, especially if the lean is getting worse, the wall is tall, or there is a path, drive or building next to it. A wall that has leaned slightly for decades may be stable, but one that has moved recently should be kept clear and assessed soon.

Does home insurance cover a collapsed garden retaining wall?

Often not, because many policies exclude garden walls unless the house is damaged by the same event, and gradual failure is usually excluded. A collapse caused by landslip or a sudden escape of water may be treated differently. Check your schedule and tell your insurer before permanent repairs start.
