How we usually approach concrete repairs
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
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
What happens during concrete repairs, step by step?
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.
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
- Chunks or flakes of concrete breaking away from edges and soffits
- Fine cracks running in straight lines along the line of the reinforcement
- Damp patches, white deposits or drips on a balcony or canopy underside

Is the ground in Greater Manchester prone to subsidence?
Greater Manchester is mostly glacial till over sandstone and mudstone, with the Lancashire coalfield beneath much of Wigan, Bolton, Salford and parts of the east. Historic mine workings, made ground and old mill sites are common. 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.
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.
