Is Hampshire prone to ground movement?

Postcode districts SO21, SO22, SO23 cover Winchester, a Hampshire town of about 46,000 people. If you are just outside Winchester, we also cover Eastleigh (7 miles), Romsey (9 miles) and Hedge End (11 miles).

Hampshire is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Hampshire: Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

What to expect when we carry out resin injection ground stabilisation

Is resin suitable?
Send photos and any reports you hold. We give a free initial assessment, and an independent engineer then checks soil type, depth to firm ground and the cause. We can arrange the engineer. Clay and tree problems need particular care.
Ground and drain checks
Trial pits or probes confirm the soil profile, and a CCTV drain survey checks for leaks and for pipes in the injection zone. Damaged drains are repaired first, so resin is not lost into them or used to treat a cause that is still active.
Design and written price
The injection depths, spacing and target lift are set out before work starts. We confirm a fixed price in writing for the treated length, the monitoring and the making good, and deal with building control where the work needs it.

Repair options we may recommend

Slab void filling and lifting

Small holes are drilled through the floor, and resin is fed into the void between the slab and the fill. As it expands it fills the gap and can lift the slab by small, controlled amounts. Floor coverings are lifted locally and the holes filled afterwards.

Best for: Sunken concrete ground floors and garage slabs

Injection beneath strip footings

Holes are drilled at close spacing along the wall, and tubes are placed at one or more depths below the footing. Resin is injected in stages from the bottom up, building a stiffened zone of ground under the wall while levels are read continuously.

Best for: Settled walls on loose or washed-out soil at shallow depth

Rules for resin injection ground stabilisation in England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Your resin injection ground stabilisation questions

What is the price of resin injection ground stabilisation in Winchester?

Guide prices for resin injection ground stabilisation in Winchester start from about £895 per metre of wall treated, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you carry out resin injection ground stabilisation in Winchester?

Yes. We take enquiries from across Winchester, including SO21, SO22, SO23, and from nearby places such as Eastleigh and Romsey. Send photos for a free initial view and we will tell you what happens next.

Does the ground around Winchester cause cracking?

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.

Is the resin harmful to the ground or drains?

Once cured, the resin is inert in the ground. The practical risk is resin travelling into a damaged drain or service duct, which is why a CCTV drain survey comes first and any defects are repaired before injection. Services near the treated zone are located and protected.

Will I need to move out?

Usually not, because most domestic injection is done from outside along the wall over one or two days. Slab treatments mean working inside, so furniture and floor coverings are moved locally. There is drilling noise, but very little dust or spoil compared with digging.
