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.
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.
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.
What to look for before calling about concrete repairs
- Rust-coloured stains or streaks running down the concrete surface
- Hollow sound when the surface is tapped with a hammer
- Damp patches, white deposits or drips on a balcony or canopy underside

How we usually approach concrete repairs
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

Is the ground in Norfolk prone to subsidence?
Norfolk is chalk covered by glacial sands, gravels and boulder clay, with fen silts in the west and soft cliffs on the north-east coast. Boulder clay areas can shrink near trees, and historic chalk mines are recorded under parts of Norwich. Only an investigation can say why a particular building has moved.
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.
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.
