Concrete repairs in Perth and Kinross
If you live in Perth and Kinross and are looking at concrete repairs, the first question is why the wall moved. Shrinkable clay is less common in Perth and Kinross than in south-east England; ground movement here is more often linked to soils, drains and trees than to mining.

How do local ground conditions affect concrete repairs in Perth and Kinross?
Perth and Kinross is largely Old Red Sandstone and Highland rock with glacial deposits and river alluvium along the Tay, which can be soft and flood-prone.
Ground movement here is more often linked to soils, drains and trees than to mining. Across Perth and Kinross, most homes are sandstone town houses and tenements, rural cottages and post-war estates.
What to look for before calling about concrete repairs
- Damp patches, white deposits or drips on a balcony or canopy underside
- Hollow sound when the surface is tapped with a hammer
- Chunks or flakes of concrete breaking away from edges and soffits
- Rust-coloured stains or streaks running down the concrete surface

How we usually approach concrete repairs
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
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
Crack injection
Cracks are sealed at the surface, then a low-viscosity resin is injected under pressure through ports until it fills the crack. A rigid resin bonds the two faces back together, while a flexible one seals live cracks against water. The choice depends on whether the crack is still moving.
Best for: Cracks letting water in, or splitting a slab or beam
What happens during concrete repairs, step by step?
Survey and tapping test
On site we tap the surface to find hollow areas, check the steel where it is exposed and note drainage. Where the extent is unclear, a cover meter, carbonation test or chloride test may be advised before repair.
Written quote
You receive a no-obligation written quote setting out the estimated area of patching, the length of crack injection, coatings and access. It becomes a fixed price in writing once the repair is specified, with any re-measure terms stated clearly.
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.
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.

Questions about concrete repairs in Perth and Kinross
Why do houses in Perth and Kinross crack?
Perth and Kinross is largely Old Red Sandstone and Highland rock with glacial deposits and river alluvium along the Tay, which can be soft and flood-prone. 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 Perth and Kinross?
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.
Can a concrete balcony be repaired rather than replaced?
In most cases, yes. Patch repairs, crack injection, a new waterproof deck and restored drips usually extend a balcony’s life considerably. Replacement is generally only needed where the steel has lost a lot of section or the balcony’s fixing to the building is compromised.
Do you repair concrete on blocks of flats?
Yes, we repair concrete on houses, flats and small commercial buildings, including balconies, walkway edges, canopies and lintels. For flats, the freeholder, managing agent or owners’ association normally instructs the work. We can price to an engineer’s schedule where one has been prepared.
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.
