Resin injection ground stabilisation in Southwark

A sunken floor slab or a settled corner in a Southwark home can sometimes be treated from the surface with expanding resin. Levels are read throughout, and monitoring afterwards shows whether the ground is holding before the cracks are repaired.

Is Greater London prone to ground movement?

Southwark takes in postcode districts including SE1, SE5, SE8, SE11, SE14, with about 310,000 residents. Neighbouring towns we cover: Lambeth (2 miles), Lewisham (3 miles) and Tower Hamlets (4 miles).

Greater London 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. Typical buildings in Greater London: Victorian and Edwardian terraces with shallow footings, inter-war semis in the outer boroughs, and converted flats and mansion blocks.

Methods for resin injection ground stabilisation

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

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

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. Injection day

    Holes are drilled, tubes placed and resin injected in stages while laser levels on the wall are watched for any rise. Most domestic jobs are done from outside, with little mess. Holes are filled and joints made good at the end.

  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

  • Cracks over a section of wall built on loose fill
  • Gaps opening beneath a ground-floor slab or path
  • A corner that has dropped but no longer moves with the seasons

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 should I budget for resin injection ground stabilisation in Southwark?

Guide prices for resin injection ground stabilisation in Southwark start from about £1,000 per metre of wall treated, including VAT, on London rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Can you survey a property in Southwark?

Yes, Southwark is covered, along with postcode districts SE1, SE5, SE8, SE11. We also cover nearby Lambeth and Lewisham.

Why do houses in Greater London crack?

Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.

Does resin injection work on clay soil?

Sometimes, but clay needs the most caution. If seasonal shrinkage from nearby trees is the cause, resin under the footing may not stop the drying below it. An engineer should look at the soil, the trees and the monitoring history before resin is chosen for a clay site.

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.
