What is the ground like in Devon?

Plymouth is in Devon and takes in postcode districts PL1, PL3, PL4. About 260,000 people live there. Nearby, we also cover Saltash (4 miles).

Shrinkable clay is less common in Devon than in south-east England. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Devon, most homes are cob and stone cottages, Victorian terraces in Exeter, Plymouth and Torbay, and post-war estates.

Which repair method suits a home in Plymouth?

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

What happens when we carry out resin injection ground stabilisation in Plymouth?

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.
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.

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.

Resin injection ground stabilisation in Plymouth: questions and answers

What is the price of resin injection ground stabilisation in Plymouth?

Guide prices for resin injection ground stabilisation in Plymouth 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.

Do you carry out resin injection ground stabilisation in Plymouth?

Yes. We take enquiries from across Plymouth, including PL1, PL3, PL4, and from nearby places such as Saltash. Send photos for a free initial view and we will tell you what happens next.

Does the ground around Plymouth cause cracking?

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.

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.
