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.
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.

Your concrete repairs questions
How much should I budget for concrete repairs in Pontypool?
Guide prices for concrete repairs in Pontypool start from about £80 per m², including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Gwent crack?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.
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.
