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
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.
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.
Rules for concrete repairs in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Questions about concrete repairs in Melksham
How much should I budget for concrete repairs in Melksham?
Guide prices for concrete repairs in Melksham start from about £90 per m², including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Wiltshire crack?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Only an investigation can say why a particular building has moved.
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.
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.
