Concrete repairs in Oban
Where flats and houses in Oban and across Argyll and Bute have concrete balconies, canopies or lintels several decades old, carbonation has had time to reach the reinforcement. That is when spalling and straight-line cracking tend to appear.

How do local ground conditions affect concrete repairs in Oban?
Oban (PA34) has around 8,500 residents and sits in Argyll and Bute.
Shrinkable clay is less common in Argyll and Bute than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Argyll and Bute: Victorian villas, stone terraces and cottages, and post-war estates.
Symptoms that point to concrete repairs
- Rust-coloured stains or streaks running down the concrete surface
- Fine cracks running in straight lines along the line of the reinforcement
- Chunks or flakes of concrete breaking away from edges and soffits

Methods for concrete repairs
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
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

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.
Rules 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.
Frequently asked questions
How much will concrete repairs cost in Oban?
Guide prices for concrete repairs in Oban start from about £80 per m², including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Oban?
Survey visits to Oban are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.
Is the ground in Argyll and Bute prone to subsidence?
Argyll is hard rock with thin glacial soils and raised beaches along the coast; mainland towns such as Helensburgh and Oban sit on steep coastal slopes. Only an investigation can say why a particular building has moved.
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.
Is spalling concrete dangerous?
It can be, mainly because pieces may fall from balconies, canopies and soffits above doors or paths. It also means the steel is losing strength over time. Fence off the area below any loose concrete, keep people off a balcony that is badly affected, and have it assessed soon.
