Parts of Lincolnshire have clay that can shrink near trees in dry spells. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Lincolnshire: Victorian terraces in Lincoln and Grimsby, fenland brick houses, seaside bungalows and post-war estates.

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

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.
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.

Your resin injection ground stabilisation questions

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

Guide prices for resin injection ground stabilisation in Grantham 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 carry out resin injection ground stabilisation in Grantham?

Yes. We take enquiries from across Grantham, including NG31, and from nearby places such as Sleaford and Newark-on-Trent. Send photos for a free initial view and we will tell you what happens next.

Does the ground around Grantham cause cracking?

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 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.

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.
