Resin injection ground stabilisation in Barnstaple

A sunken floor slab or a settled corner in a Barnstaple 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?

Barnstaple, Devon: about 32,000 residents across postcode districts EX31, EX32. We also take enquiries from nearby Bideford (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.

How we usually approach 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

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

What happens during resin injection ground stabilisation, step by step?

  1. 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.

  2. 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.

  3. 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.

What to look for before calling about resin injection ground stabilisation

  • Gaps opening beneath a ground-floor slab or path
  • Settlement after a drain leak has been found and repaired
  • 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.

Questions about resin injection ground stabilisation in Barnstaple

How much should I budget for resin injection ground stabilisation in Barnstaple?

Guide prices for resin injection ground stabilisation in Barnstaple 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 Barnstaple?

Yes, Barnstaple is covered, along with postcode districts EX31, EX32. We also cover nearby Bideford.

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 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.
