Why does the ground in Wiltshire matter for concrete repairs?

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.

Ground movement here is more often linked to soils, drains and trees than to mining. Housing stock in Wiltshire: Stone cottages, railway terraces in Swindon, and large post-war and new-build estates.

Repair options we may recommend

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

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

What to expect when we carry out concrete repairs

  1. 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.

  2. 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.

  3. 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.

Is it time for concrete repairs? Common signs

  • Exposed steel bars showing where concrete has fallen away
  • Fine cracks running in straight lines along the line of the reinforcement
  • Chunks or flakes of concrete breaking away from edges and soffits
  • Damp patches, white deposits or drips on a balcony or canopy underside

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.

Your concrete repairs questions

Does the ground around Swindon cause cracking?

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. 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 Wiltshire?

On South West rates, concrete repairs starts from about £90 per m², including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

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.

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.
