Concrete repairs in Aberdeen and Aberdeenshire
Concrete repairs in Aberdeen and Aberdeenshire starts with the ground. Clay shrinkage is less of a concern in Aberdeen and Aberdeenshire, so other causes such as drains, poor footings or older walls are checked first, and the buildings here are mostly granite tenements and terraces in Aberdeen, so the repair has to suit both.

What is the ground like in Aberdeen and Aberdeenshire?
The north-east is mostly granite and other hard rock with glacial till and sands, so clay shrinkage is uncommon. Granite buildings, older lime mortars and coastal exposure shape most repairs.
Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Aberdeen and Aberdeenshire: granite tenements and terraces in Aberdeen, fishing-town cottages and post-war estates.

Which repair method suits a home in Aberdeen and Aberdeenshire?
Recasting or strengthening
Where steel has lost much of its section, or a lintel or canopy is too far gone to patch, the element is propped and rebuilt, replaced or strengthened to an engineer’s design. It is less common, but sometimes the more lasting option for small canopies and old precast lintels.
Best for: Badly corroded lintels, canopies and balcony edges
Protective coatings and sealing
After repair, an anti-carbonation coating, a waterproof deck membrane on a balcony, or a penetrating sealer slows the return of moisture and carbon dioxide. Restoring drips, upstands and falls so water drains away is as important as the coating itself.
Best for: Extending the life of repaired balconies and canopies
Patch repair
Loose and contaminated concrete is broken out behind the bar, the steel is cleaned of rust and primed, and the section is rebuilt with a repair mortar. The edges are cut square so the patch does not feather out and fail. A protective coating may be applied over the whole surface afterwards.
Best for: Localised spalling around rusting bars
What happens when we carry out concrete repairs in Aberdeen and Aberdeenshire?
Photos and a description
Send photos of the damage close up and from a distance, plus the whole balcony, canopy or elevation. Tell us roughly how old the building is and whether anything has fallen, so we can judge whether to make it safe first.
Engineer where needed
If the steel has lost significant section, or the element carries a balcony, stair or wall, an independent chartered structural engineer is appointed to assess and specify. We can arrange this, and the repair follows their scope.
Break out, repair, protect
Damaged concrete is cut back to sound material, steel cleaned and primed, and the section rebuilt and cured. Cracks are injected, then the surface is coated and drainage details put right so water runs off rather than sitting.
Signs you may need concrete repairs
- Damp patches, white deposits or drips on a balcony or canopy underside
- Chunks or flakes of concrete breaking away from edges and soffits
- Fine cracks running in straight lines along the line of the reinforcement
- Rust-coloured stains or streaks running down the concrete surface
Do you need approval for concrete repairs in Scotland?
In Scotland, small repairs often do not need a building warrant, but structural alterations and strengthening generally do. Check with the council’s building standards service if unsure; there is no Party Wall Act in Scotland.

Concrete repairs in Aberdeen and Aberdeenshire: questions and answers
Is the ground in Aberdeen and Aberdeenshire prone to subsidence?
The north-east is mostly granite and other hard rock with glacial till and sands, so clay shrinkage is uncommon. Granite buildings, older lime mortars and coastal exposure shape most repairs. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will concrete repairs cost in Aberdeen and Aberdeenshire?
On Scotland rates, concrete repairs starts from about £80 per m², including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
What is spalling concrete?
Spalling is concrete breaking away from the surface in flakes or chunks. In reinforced concrete it is usually caused by the steel inside rusting and expanding, which pushes the cover off. It often follows a straight line where a bar sits close to the surface, with rust staining nearby.
Why does concrete crack and rust?
Concrete cracks as it shrinks, moves with temperature or carries more load than intended. Steel inside it rusts when carbonation or salts reach it and moisture gets in. The two feed each other: cracks let water in, and rusting steel expands and cracks the concrete further.
What is carbonation in concrete?
Carbonation is the gradual reaction between carbon dioxide in the air and concrete, which lowers its alkalinity from the surface inward. Alkaline concrete protects the steel inside, so when carbonation reaches the bars, they can start to rust. A simple test on a freshly broken surface shows how deep it has gone.
