What should you know about the ground under Llanelli?
Llanelli (SA15) has around 50,000 residents and sits in Dyfed. If you are just outside Llanelli, we also cover Gorseinon (5 miles), Swansea (10 miles) and Ammanford (11 miles).
Most of Dyfed is on firmer ground than the clay belts of the south-east. Parts of Dyfed lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Dyfed: Stone cottages, Victorian terraces in Llanelli and Carmarthen, and post-war estates.
Methods for retaining wall repairs
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
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
- Water seeping through joints, or white salt staining, after rain
- Bricks or blocks pushed out of line, or coping stones sliding off
- Wall leaning forward, or bulging out in the middle of its length

Rules for retaining wall repairs in Wales
In Wales, the Welsh version of the Building Regulations applies.

Frequently asked questions
How much should I budget for retaining wall repairs in Llanelli?
Guide prices for retaining wall repairs in Llanelli start from about £460 per wall, including VAT, on Wales 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 Llanelli?
We do. Llanelli and the surrounding area are covered, including nearby Gorseinon and Swansea. A free initial assessment from your photos is the first step.
Why do houses in Dyfed crack?
The western edge of the South Wales coalfield lies beneath Llanelli, Ammanford and parts of Pembrokeshire, while the rest of the area is older hard rock with glacial deposits in the valleys. 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.
What are weep holes in a retaining wall?
Weep holes are small openings near the base of a retaining wall that let water drain out from the soil behind it. Without them, water builds up and adds hydrostatic pressure that can push the wall over. They work best with a drainage layer behind the wall, and they need to be kept clear.
