Concrete repairs in Blyth
Spalling concrete on a Blyth balcony, canopy or lintel almost always starts with the steel inside. Once carbonation or salts reach the bars, they rust and swell, and the concrete breaks away along their line until the steel is repaired and protected.

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
What to expect when we carry out concrete repairs
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.
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.
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 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.
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.
