Concrete repairs in Flint
Spalling concrete on a Flint 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.

Is Clwyd prone to ground movement?
Postcode districts CH6 cover Flint, a Clwyd town of about 26,000 people. We also take enquiries from nearby Connah's Quay (5 miles), Mold (5 miles) and Buckley (6 miles).
Clay soils are found in parts of Clwyd. Parts of Clwyd lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Clwyd, most homes are brick colliery terraces, seaside villas in Rhyl and Colwyn Bay, and post-war estates.
What happens when we carry out concrete repairs in Flint?
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.
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
- Damp patches, white deposits or drips on a balcony or canopy underside
- Rust-coloured stains or streaks running down the concrete surface

Which repair method suits a home in Flint?
Recasting or strengthening
Where steel has lost much of its section, or a lintel or canopy is too far gone to patch, the element is propped and rebuilt, replaced or strengthened to an engineer’s design. It is less common, but sometimes the more lasting option for small canopies and old precast lintels.
Best for: Badly corroded lintels, canopies and balcony edges
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
Rules for concrete repairs in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.

Is the ground in Clwyd prone to subsidence?
The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock. 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.
Is spalling concrete dangerous?
It can be, mainly because pieces may fall from balconies, canopies and soffits above doors or paths. It also means the steel is losing strength over time. Fence off the area below any loose concrete, keep people off a balcony that is badly affected, and have it assessed soon.
