Resin injection ground stabilisation in Norwich
For a Norwich house that has settled over loose fill or ground washed out by a drain, expanding resin can firm the soil in a day or two. It is done through small drilled holes, so gardens and paths are left largely as they were.

What should you know about the ground under Norwich?
Norwich (NR1, NR2, NR3, NR4, NR5) has around 140,000 residents and sits in Norfolk. Nearby places we cover include East Dereham (16 miles), Great Yarmouth (18 miles) and Lowestoft (22 miles).
Parts of Norfolk have clay that can shrink near trees in dry spells. Ground movement here is more often linked to soils, drains and trees than to mining. Across Norfolk, most homes are flint and brick cottages, Victorian terraces in Norwich and Great Yarmouth, and post-war bungalows.
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

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
- Settlement after a drain leak has been found and repaired
- Gaps opening beneath a ground-floor slab or path
- 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.
Frequently asked questions
What is the price of resin injection ground stabilisation in Norwich?
Guide prices for resin injection ground stabilisation in Norwich start from about £840 per metre of wall treated, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Yes, Norwich is covered, along with postcode districts NR1, NR2, NR3, NR4. We also cover nearby East Dereham and Great Yarmouth.
Does the ground around Norwich cause cracking?
Norfolk is chalk covered by glacial sands, gravels and boulder clay, with fen silts in the west and soft cliffs on the north-east coast. Boulder clay areas can shrink near trees, and historic chalk mines are recorded under parts of Norwich. Only an investigation can say why a particular building has moved.
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.
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.
