Resin injection ground stabilisation in Richmond upon Thames
Homeowners in Richmond 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.

Why does the ground in Greater London matter for resin injection ground stabilisation?
Richmond upon Thames is one of the 32 London boroughs, with around 200,000 residents in districts such as TW1, TW2, TW7, TW9, TW10. Nearby places we cover include Hounslow (2 miles), East Molesey (4 miles) and Kingston upon Thames (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. Housing stock 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
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

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.
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.
Symptoms that point to resin injection ground stabilisation
- Settlement after a drain leak has been found and repaired
- Cracks over a section of wall built on loose fill
- Sinking that trial pits trace to loose or washed-out soil

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.

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 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.
How long does resin injection last?
The cured resin itself is stable and does not break down in normal ground. Whether the repair lasts depends on whether the cause of movement has been removed, which is why drains are checked and monitoring follows. If the ground was the only problem, the treatment is usually long-term.
