Why does the ground in Edinburgh and the Lothians matter for retaining wall repairs?

Edinburgh is volcanic and sedimentary rock with glacial till, while the Midlothian and East Lothian coalfields and oil-shale workings in West Lothian have left recorded mine workings and bings.

Parts of Edinburgh and the Lothians lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Edinburgh and the Lothians: Sandstone tenements and Georgian terraces, miners' rows, bungalows and post-war estates.

What happens during retaining wall repairs, step by step?

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.
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.

What to look for before calling about retaining wall repairs

Wall leaning forward, or bulging out in the middle of its length
No weep holes, or weep holes that never seem to drain
Bricks or blocks pushed out of line, or coping stones sliding off
Ground cracking or sinking along the top of the wall

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

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

Retaining wall: drainage behind the wall, weep holes and a proper footing. Indicative drawing, not to scale.

Do you need approval for retaining wall repairs in Scotland?

In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.

Questions about retaining wall repairs in Edinburgh and the Lothians

Why do houses in Edinburgh and the Lothians crack?

Edinburgh is volcanic and sedimentary rock with glacial till, while the Midlothian and East Lothian coalfields and oil-shale workings in West Lothian have left recorded mine workings and bings. Parts of Edinburgh and the Lothians lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will retaining wall repairs cost in Edinburgh and the Lothians?

On Scotland rates, retaining wall repairs starts from about £475 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.

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.
