What is the ground like in Derbyshire?

East Derbyshire, including Chesterfield, Ilkeston and Heanor, lies on the Coal Measures with a long history of shallow and deep coal mining. The Peak District to the west is limestone and gritstone, and Derby itself sits largely on Mercia Mudstone.

Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Derbyshire, most homes are brick terraces in former mining towns, gritstone cottages in the Peak, and inter-war and post-war semis.

What to look for before calling about concrete repairs

  • Exposed steel bars showing where concrete has fallen away
  • Chunks or flakes of concrete breaking away from edges and soffits
  • Fine cracks running in straight lines along the line of the reinforcement
  • Hollow sound when the surface is tapped with a hammer

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

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

What happens during concrete repairs, step by step?

  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. 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.

  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.

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.

Questions about concrete repairs in Derbyshire

Why do houses in Derbyshire crack?

East Derbyshire, including Chesterfield, Ilkeston and Heanor, lies on the Coal Measures with a long history of shallow and deep coal mining. The Peak District to the west is limestone and gritstone, and Derby itself sits largely on Mercia Mudstone. Parts of Derbyshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will concrete repairs cost in Derbyshire?

On East Midlands rates, concrete repairs starts from about £85 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.

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.

Can you repair a cracked concrete lintel?

Often, yes. Spalling and small cracks in a concrete lintel can be patch repaired and the steel treated. If the lintel is badly cracked, sagging or the bars have lost much of their section, replacement is usually better, and the opening is propped while it is done.
