How do local ground conditions affect concrete repairs in Havant?
We cover Havant and its postcode districts PO9, part of Hampshire, with a population of roughly 46,000. Neighbouring towns we cover: Emsworth (2 miles), Waterlooville (3 miles) and Hayling Island (5 miles).
Much of Hampshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Hampshire: Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

How we usually approach concrete repairs
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
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
What happens during concrete repairs, step by step?
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.
What to look for before calling about concrete repairs
- Chunks or flakes of concrete breaking away from edges and soffits
- Hollow sound when the surface is tapped with a hammer
- Exposed steel bars showing where concrete has fallen away
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.
Questions about concrete repairs in Havant

Is the ground in Hampshire prone to subsidence?
Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement near trees. Only an investigation can say why a particular building has moved.
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.
Can you repair a cracked concrete lintel?
Often, yes. Spalling and small cracks in a concrete lintel can be patch repaired and the steel treated. If the lintel is badly cracked, sagging or the bars have lost much of their section, replacement is usually better, and the opening is propped while it is done.
