Retaining wall repairs in Littlehampton
A garden retaining wall in Littlehampton 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.

Which repair method suits a home in Littlehampton?
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 Littlehampton?
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.
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.

Is the ground in West Sussex prone to subsidence?
North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. 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.
Who is responsible for a retaining wall between two properties?
Usually the owner of the higher ground, because the wall holds up their land, but it depends on your title deeds and how the wall came to be built. Check the deeds first, take advice if it is unclear, and agree the repair with your neighbour before work starts.
