Resin injection ground stabilisation in Daventry
Homeowners in Daventry often hear of resin injection as a quicker alternative to underpinning. It can be, provided the problem lies in the upper layers of soil and the drains have been checked, because resin stabilises ground but cannot stop an active leak.

What should you know about the ground under Daventry?
Daventry is in Northamptonshire and takes in postcode districts NN11. About 28,000 people live there. If you are just outside Daventry, we also cover Rugby (9 miles), Northampton (12 miles) and Leamington Spa (15 miles).
Shrinkable clay is widespread in Northamptonshire. Historic ironstone working has left disturbed ground in places. Across Northamptonshire, most homes are ironstone and limestone cottages, Victorian terraces in Northampton and Kettering, and new-town estates in Corby.
What happens during resin injection ground stabilisation, step by step?
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.
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
- Settlement after a drain leak has been found and repaired

- Floor slab dropping or hollow-sounding near one external wall

How we usually approach 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
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.
Questions about resin injection ground stabilisation in Daventry
How much will resin injection ground stabilisation cost in Daventry?
Guide prices for resin injection ground stabilisation in Daventry start from about £785 per metre of wall treated, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Daventry?
Yes, Daventry is covered, along with postcode districts NN11. We also cover nearby Rugby and Northampton.
Is the ground in Northamptonshire prone to subsidence?
Northamptonshire sits largely on Lias clay and Jurassic ironstones and limestones, with historic ironstone quarrying around Corby and Kettering. The clay vales are prone to shrinkage near trees. Only an investigation can say why a particular building has moved.
Can resin injection lift my house back to level?
It can produce small, controlled lifts, but it is not a way to jack a house back to its original position. The main aim is to stabilise the ground. Laser levels are watched throughout so injection stops before the lift strains the walls or opens new cracks.
Does resin injection work on clay soil?
Sometimes, but clay needs the most caution. If seasonal shrinkage from nearby trees is the cause, resin under the footing may not stop the drying below it. An engineer should look at the soil, the trees and the monitoring history before resin is chosen for a clay site.
