Resin injection ground stabilisation in Salisbury
For a Salisbury house that has settled over loose fill or ground washed out by a drain, expanding resin can firm the soil in a day or two. It is done through small drilled holes, so gardens and paths are left largely as they were.

Why does the ground in Wiltshire matter for resin injection ground stabilisation?
Salisbury (SP1, SP2) has around 45,000 residents and sits in Wiltshire. If you are just outside Salisbury, we also cover Romsey (14 miles), Andover (16 miles) and Totton (17 miles).
Wiltshire has a mix of ground, with clay in some places and firmer rock in others. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Wiltshire: stone cottages, railway terraces in Swindon, and large post-war and new-build estates.

How we usually approach 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
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 during resin injection ground stabilisation, step by step?
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.
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
- Floor slab dropping or hollow-sounding near one external wall
- Settlement after a drain leak has been found and repaired
- Cracks over a section of wall built on loose fill
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 Salisbury
What is the price of resin injection ground stabilisation in Salisbury?
Guide prices for resin injection ground stabilisation in Salisbury start from about £825 per metre of wall treated, including VAT, on South West 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 Salisbury?
Yes. We take enquiries from across Salisbury, including SP1, SP2, and from nearby places such as Romsey and Andover. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Salisbury cause cracking?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. 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.
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.
