Retaining wall repairs in Clevedon
A garden retaining wall in Clevedon holds back far more weight than it looks, and the push increases every time the soil behind it gets wet. Most leaning or bulging walls turn out to have poor drainage, thin construction or shallow footings, often all three.

What is the ground like in Somerset?
With roughly 21,000 people, Clevedon spans postcode districts BS21 in Somerset. We also take enquiries from nearby Nailsea (4 miles), Portishead (5 miles) and Weston-super-Mare (8 miles).
Somerset has a mix of ground, with clay in some places and firmer rock in others. Parts of Somerset lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Somerset: Bath stone Georgian terraces, Victorian houses in Taunton and Weston-super-Mare, and post-war estates.
Which repair method suits a home in Clevedon?
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
Drainage and minor repairs
Blocked weep holes are cleared or new ones drilled, and where practical a drainage layer is formed behind the wall with an outlet at its base. Loose copings are rebedded, open joints repointed and a few damaged bricks replaced. For a low wall that has not moved much, this can be enough.
Best for: Low walls that are damp or slightly weathered but still upright
What happens when we carry out retaining wall repairs in Clevedon?
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.
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.
Signs you may need retaining wall repairs
- Water seeping through joints, or white salt staining, after rain
- Ground cracking or sinking along the top of the wall
- Wall leaning forward, or bulging out in the middle of its length

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.
Retaining wall repairs in Clevedon: questions and answers
How much will retaining wall repairs cost in Clevedon?

Do you cover Clevedon?

Is the ground in Somerset prone to subsidence?
Somerset mixes Lias clays, Mercia Mudstone, limestone hills and the peat and alluvium of the Levels around Bridgwater, which can settle. The former Somerset coalfield around Radstock and Midsomer Norton left recorded workings. Only an investigation can say why a particular building has moved.
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.
Can a bulging retaining wall be saved?
Sometimes, if the bulge is small, the wall is low and the cause is mainly poor drainage. Improving drainage and repairing the face may stop further movement. A wall that has bulged a lot, cracked through or moved at its base usually needs that section rebuilding on a proper footing.
