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

What should you know about the ground under Havering?
We cover the whole of Havering, including postcode districts RM1, RM2, RM3, RM11, RM12; about 260,000 people live in the borough. Nearby, we also cover South Ockendon (4 miles), Barking and Dagenham (4 miles) and Brentwood (5 miles).
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. 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.
From first photo to finished repair
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
- A corner that has dropped but no longer moves with the seasons
- Gaps opening beneath a ground-floor slab or path
- Sinking that trial pits trace to loose or washed-out soil

Methods for resin injection ground stabilisation
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
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 should I budget for resin injection ground stabilisation in Havering?
Guide prices for resin injection ground stabilisation in Havering 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 Havering?
Yes. We take enquiries from across Havering, including RM1, RM2, RM3, RM11, and from nearby places such as South Ockendon and Barking and Dagenham. Send photos for a free initial view and we will tell you what happens next.
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.
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.
