Resin injection ground stabilisation in Sutton
A sunken floor slab or a settled corner in a Sutton 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.

Much of Greater London 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 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
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
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

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.
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.
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
- Sinking that trial pits trace to loose or washed-out soil
- Cracks over a section of wall built on loose fill
- Floor slab dropping or hollow-sounding near one external wall

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.

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.
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.
