Resin injection ground stabilisation in Gainsborough
Homeowners in Gainsborough 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.

Methods for 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
From first photo to finished repair
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.
Symptoms that point to resin injection ground stabilisation
- Sinking that trial pits trace to loose or washed-out soil
- A corner that has dropped but no longer moves with the seasons
- Settlement after a drain leak has been found and repaired

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 Lincolnshire prone to subsidence?
Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. Only an investigation can say why a particular building has moved.
How do I know if my house is suitable?
An engineer decides, based on the soil type, the depth to firm ground and the cause of movement. Send us photos and any reports for a free initial assessment. We will say honestly if resin looks unlikely to suit and a different repair is worth considering.
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.
