Resin injection ground stabilisation in Kingston upon Thames
Homeowners in Kingston upon Thames 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 Kingston upon Thames?
Kingston upon Thames is one of the 32 London boroughs, with around 170,000 residents in districts such as KT1, KT2, KT3, KT4, KT5. Nearby, we also cover East Molesey (3 miles), Ewell (3 miles) and Esher (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. What you mostly find across Greater London: Victorian and Edwardian terraces with shallow footings, inter-war semis in the outer boroughs, and converted flats and mansion blocks.
What happens during resin injection ground stabilisation, step by step?
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.
What to look for before calling about resin injection ground stabilisation
- A corner that has dropped but no longer moves with the seasons
- Floor slab dropping or hollow-sounding near one external wall
- Sinking that trial pits trace to loose or washed-out soil

How we usually approach 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.
Questions about resin injection ground stabilisation in Kingston upon Thames
How much will resin injection ground stabilisation cost in Kingston upon Thames?
Guide prices for resin injection ground stabilisation in Kingston upon Thames 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.
Do you cover Kingston upon Thames?
Yes, Kingston upon Thames is covered, along with postcode districts KT1, KT2, KT3, KT4. We also cover nearby East Molesey and Ewell.
Is the ground in Greater London prone to subsidence?
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.
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.
How do I know if my house is suitable?
An engineer decides, based on the soil type, the depth to firm ground and the cause of movement. Send us photos and any reports for a free initial assessment. We will say honestly if resin looks unlikely to suit and a different repair is worth considering.
