Resin injection ground stabilisation in Longfield
Resin injection can suit some Longfield 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.

Is Kent prone to ground movement?
Longfield (DA3, DA4, DA13) has around 17,000 residents and sits in Kent. Nearby places we cover include Swanscombe (3 miles), Gravesend (4 miles) and Dartford (5 miles).
Shrinkable clay is widespread in Kent. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.
Signs you may need resin injection ground stabilisation
- Floor slab dropping or hollow-sounding near one external wall
- A corner that has dropped but no longer moves with the seasons
- Sinking that trial pits trace to loose or washed-out soil

Which repair method suits a home in Longfield?
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
What happens when we carry out resin injection ground stabilisation in Longfield?
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.
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.
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 Kent prone to subsidence?
North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. Only an investigation can say why a particular building has moved.
Will I need to move out?
Usually not, because most domestic injection is done from outside along the wall over one or two days. Slab treatments mean working inside, so furniture and floor coverings are moved locally. There is drilling noise, but very little dust or spoil compared with digging.
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.
