Concrete repairs in Oswestry
Where flats and houses in Oswestry and across Shropshire 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 Shropshire prone to ground movement?
Oswestry (SY11) has around 19,000 residents and sits in Shropshire. Nearby places we cover include Shrewsbury (16 miles) and Chester (24 miles).
Parts of Shropshire have clay that can shrink near trees in dry spells. Parts of Shropshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Shropshire, most homes are timber-framed and brick town houses, industrial terraces around Telford, and new-town estates.

How we usually approach 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
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?
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.
What to look for before calling about concrete repairs
- Hollow sound when the surface is tapped with a hammer
- Damp patches, white deposits or drips on a balcony or canopy underside
- Chunks or flakes of concrete breaking away from edges and soffits
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 Shropshire prone to subsidence?
Shropshire has very varied rock, from Mercia Mudstone on the north Shropshire plain to the Coalbrookdale coalfield under Telford, where historic shallow coal, clay and ironstone workings are widespread. Only an investigation can say why a particular building has moved.
What is carbonation in concrete?
Carbonation is the gradual reaction between carbon dioxide in the air and concrete, which lowers its alkalinity from the surface inward. Alkaline concrete protects the steel inside, so when carbonation reaches the bars, they can start to rust. A simple test on a freshly broken surface shows how deep it has gone.
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.
