Resin injection ground stabilisation in Southampton

Homeowners in Southampton often hear of resin injection as a quicker alternative to underpinning. It can be, provided the problem lies in the upper layers of soil and the drains have been checked, because resin stabilises ground but cannot stop an active leak.

What should you know about the ground under Southampton?

With roughly 270,000 people, Southampton spans postcode districts SO14, SO15, SO17 in Hampshire. Nearby places we cover include Hythe (3 miles), Totton (4 miles) and Hedge End (5 miles).

Shrinkable clay is widespread in Hampshire. 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.

From first photo to finished repair

  1. 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.

  2. 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.

  3. Level monitoring

    Readings after treatment show whether the ground is holding. Once they are steady, cracks are stitched and redecoration can follow. If a section keeps moving, the engineer decides whether further injection or a different method is needed.

Symptoms that point to resin injection ground stabilisation

  • A corner that has dropped but no longer moves with the seasons
  • Settlement after a drain leak has been found and repaired
  • Sinking that trial pits trace to loose or washed-out soil

Methods for resin injection ground stabilisation

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

Resin alongside other repairs

Injection often forms one part of a wider scheme: drains repaired first, resin under the affected section, then crack stitching and making good once readings settle. On a mixed site, one wall may suit resin while another needs conventional underpinning instead.

Best for: Localised settlement within a broader subsidence repair

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.

Frequently asked questions

How much will resin injection ground stabilisation cost in Southampton?

Guide prices for resin injection ground stabilisation in Southampton 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 cover Southampton?

Yes, Southampton is covered, along with postcode districts SO14, SO15, SO17. We also cover nearby Hythe and Totton.

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.

Is resin injection better than underpinning?

It is better for some jobs and unsuitable for others. Resin is quicker and less disruptive where the problem is loose or washed-out soil close to the footing. Underpinning or mini-piles are usually the safer choice for deep soft ground or clay dried by trees that cannot be removed.

Can resin injection lift my house back to level?

It can produce small, controlled lifts, but it is not a way to jack a house back to its original position. The main aim is to stabilise the ground. Laser levels are watched throughout so injection stops before the lift strains the walls or opens new cracks.
