What should you know about the ground under Edinburgh and the Lothians?

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. Typical buildings in Edinburgh and the Lothians: Sandstone tenements and Georgian terraces, miners' rows, bungalows and post-war estates.

What to expect when we carry out bowing wall repairs

Assess the bow
We look at where the wall bows, how far it is out of plumb and how the floors and roof meet it. Photographs from your phone held flat against the wall often show the shape clearly before anyone visits.
Decide restrain or rebuild
If the wall is badly out of plumb, has bricks crushing or follows removed internal walls, we recommend an engineer, and can arrange one. Their view sets whether restraint is enough or a section needs rebuilding.
Fit the ties and straps
Ties are drilled through and fixed, or straps fitted and secured, at the spacing specified. Any rebuild is carried out at this stage, with temporary propping in place until the new brickwork has gained strength.

Repair options we may recommend

Lateral restraint straps

Galvanised or stainless straps are fixed across three or more joists or rafters, turned down against the inside face of the wall and fixed into the masonry. They work well at ceiling and roof level, where the fixings stay hidden.

Best for: Gables and walls bowing near ceiling or roof level

Stitching a delaminating wall

Where the layers of a solid wall have separated, long stainless ties are drilled in from the face and bonded into the inner layer to bind the wall together again. This is often combined with restraint ties, so the wall is both reconnected through its thickness and tied back to the structure.

Best for: Solid walls where the outer layer has pulled away

Partial rebuild

A section that has bowed beyond safe limits, or where bricks have crushed, is propped, taken down and rebuilt plumb with restraint built in. It is the most disruptive option, so it is kept to the area that genuinely needs it.

Best for: Badly distorted sections that cannot be tied back

Do you need approval for bowing 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.

Your bowing wall repairs questions

Is the ground in Edinburgh and the Lothians prone to subsidence?

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 bowing wall repairs cost in Edinburgh and the Lothians?

On Scotland rates, bowing wall repairs starts from about £950 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

What is lateral restraint?

Lateral restraint is the connection that stops a wall moving sideways, provided by tying it to the floors and roof. Older houses often have little or none, especially where joists run parallel to the wall. Remedial ties and straps add that connection after the event.

Do restraint ties show on the outside?

Some do and some do not. Certain ties leave a small round or square plate on the outside face, while others are fully recessed and pointed over. Straps fitted from inside leave no outside trace at all. We agree the finish with you before work starts.

Can a bowing wall be pushed back straight?

Usually not. Masonry rarely returns to plumb without cracking, so the normal aim is to stop further movement and leave the wall where it is. If the bow is too great to accept, that section is rebuilt rather than forced back.
