Resin injection ground stabilisation in Bideford
A sunken floor slab or a settled corner in a Bideford 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 is the ground like in Devon?
Bideford, Devon: about 29,000 residents across postcode districts EX39. If you are just outside Bideford, we also cover Barnstaple (8 miles).
Most of Devon is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. What you mostly find across Devon: cob and stone cottages, Victorian terraces in Exeter, Plymouth and Torbay, and post-war estates.

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
From first photo to finished repair
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.
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
- Cracks over a section of wall built on loose fill
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 Bideford?
Guide prices for resin injection ground stabilisation in Bideford start from about £825 per metre of wall treated, including VAT, on South West 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 Bideford?
Yes, Bideford is covered, along with postcode districts EX39. We also cover nearby Barnstaple.
Why do houses in Devon crack?
Devon's ground is mostly older mudstones, sandstones and granite, so shrinkable-clay subsidence is less widespread than further east. Older solid-walled and cob buildings, steep sites and retaining walls are the more common structural concerns. 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 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.
