Concrete repairs in Tyne and Wear
Concrete repairs in Tyne and Wear starts with the ground. Tyne and Wear has a mix of ground, with clay in some places and firmer rock in others, and the buildings here are mostly Tyneside flats and terraces, so the repair has to suit both.

Why does the ground in Tyne and Wear matter for concrete repairs?
Tyne and Wear lies on the Durham and Northumberland coalfield, with old shallow workings recorded beneath parts of Newcastle, Gateshead and Sunderland, mostly under a cover of glacial clay.
Historic coal workings are recorded beneath parts of Tyne and Wear, and a coal mining search is worth checking where movement is unexplained. Across Tyne and Wear, most homes are Tyneside flats and terraces, Victorian villas, inter-war council estates and post-war semis.
Which repair method suits a home in Tyne and Wear?
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 when we carry out concrete repairs in Tyne and Wear?
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.
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.
Signs you may need concrete repairs
- 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
- 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.

Concrete repairs in Tyne and Wear: questions and answers
Is the ground in Tyne and Wear prone to subsidence?
Tyne and Wear lies on the Durham and Northumberland coalfield, with old shallow workings recorded beneath parts of Newcastle, Gateshead and Sunderland, mostly under a cover of glacial clay. Historic coal workings are recorded beneath parts of Tyne and Wear, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.
How much will concrete repairs cost in Tyne and Wear?
On North East rates, concrete repairs starts from about £80 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 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.
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.
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.
