Concrete repairs in Falmouth
Spalling concrete on a Falmouth 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.

What is the ground like in Cornwall?
Postcode districts TR11 cover Falmouth, a Cornwall town of about 32,000 people. Neighbouring towns we cover: Truro (8 miles), Redruth (9 miles) and Camborne (11 miles).
Most of Cornwall is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Typical buildings in Cornwall: Granite and slate-stone cottages, cob buildings, Victorian terraces and post-war estates.
What happens when we carry out concrete repairs in Falmouth?
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.
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.
Signs you may need concrete repairs
- Fine cracks running in straight lines along the line of the reinforcement
- Chunks or flakes of concrete breaking away from edges and soffits
- Rust-coloured stains or streaks running down the concrete surface
How much will concrete repairs cost in Falmouth?

|---|---|---|

Which repair method suits a home in Falmouth?
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
Rules 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.

Is the ground in Cornwall prone to subsidence?
Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. 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.
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.
