Why does the ground in Berkshire matter for concrete repairs?
East Berkshire is largely London Clay with Thames terrace gravels along the river, while the west rises onto chalk downland. Houses on the clay near Slough, Windsor and Bracknell are the ones most exposed to shrink-swell movement.
Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Berkshire: Victorian and Edwardian terraces in Reading and Windsor, 1930s semis, and large post-war new-town estates around Bracknell.
Symptoms that point to concrete repairs
- Damp patches, white deposits or drips on a balcony or canopy underside
- Hollow sound when the surface is tapped with a hammer
- 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
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
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.
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.
Do you need approval 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.

Frequently asked questions
Is the ground in Berkshire prone to subsidence?
East Berkshire is largely London Clay with Thames terrace gravels along the river, while the west rises onto chalk downland. Houses on the clay near Slough, Windsor and Bracknell are the ones most exposed to shrink-swell movement. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will concrete repairs cost in Berkshire?
On South East rates, concrete repairs starts from about £95 per m², including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Can a concrete balcony be repaired rather than replaced?
In most cases, yes. Patch repairs, crack injection, a new waterproof deck and restored drips usually extend a balcony’s life considerably. Replacement is generally only needed where the steel has lost a lot of section or the balcony’s fixing to the building is compromised.
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.
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.
