Resin injection ground stabilisation in Kempston
Resin injection can suit some Kempston homes well and others not at all. The deciding factors are the soil below the footing, how deep firm ground lies and whether the cause of movement, such as a leaking drain, has already been dealt with.

What is the ground like in Bedfordshire?
Kempston is in Bedfordshire and takes in postcode districts MK42. About 20,000 people live there. Nearby places we cover include Bedford (2 miles), Newport Pagnell (10 miles) and Biggleswade (10 miles).
Much of Bedfordshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Bedfordshire: Victorian terraces in Bedford and Luton, large inter-war and post-war estates, and newer estates on former clay pits and brickfields.
Repair options we may recommend
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
What to expect when we carry out resin injection ground stabilisation
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.
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.

Is the ground in Bedfordshire prone to subsidence?
Much of Bedfordshire sits on Oxford Clay and Gault Clay, with chalk rising towards the Chilterns in the south. The clay vales shrink in dry summers and swell in wet winters, which is why seasonal cracking is common around Bedford. 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.
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.
