Concrete repairs in Widnes
Where flats and houses in Widnes and across Cheshire 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.

Is Cheshire prone to ground movement?
Widnes, Cheshire: about 61,000 residents across postcode districts WA7, WA8. We also take enquiries from nearby Warrington (7 miles), Ellesmere Port (9 miles) and Ashton-in-Makerfield (9 miles).
Parts of Cheshire have clay that can shrink near trees in dry spells. Historic brine and salt working has caused ground movement in parts of Cheshire in the past. Typical buildings in Cheshire: Brick terraces in Crewe, Northwich and Warrington, Victorian villas in Chester, and inter-war and post-war semis.
From first photo to finished repair
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.
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.
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.
Symptoms that point to concrete repairs
- Fine cracks running in straight lines along the line of the reinforcement
- Rust-coloured stains or streaks running down the concrete surface
- Exposed steel bars showing where concrete has fallen away

Methods for 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
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
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.

Is the ground in Cheshire prone to subsidence?
Most of Cheshire is glacial till over Mercia Mudstone. Around Northwich and the Weaver valley, historic salt and brine extraction has caused subsidence in the past, and a separate brine subsidence compensation scheme exists for parts of the county. 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.
