How we usually approach retaining wall repairs
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
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
What happens during retaining wall repairs, step by step?
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.
Questions about retaining wall repairs in Irlam
How much should I budget for retaining wall repairs in Irlam?
Guide prices for retaining wall repairs in Irlam start from about £480 per wall, including VAT, on North West 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 Irlam?
Yes, Irlam is covered, along with postcode districts M31, M41, M44. We also cover nearby Sale and Altrincham.
Why do houses in Greater Manchester crack?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. Only an investigation can say why a particular building has moved.
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.
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.
