Resin injection ground stabilisation in Perth
A sunken floor slab or a settled corner in a Perth home can sometimes be treated from the surface with expanding resin. Levels are read throughout, and monitoring afterwards shows whether the ground is holding before the cracks are repaired.

Methods for resin injection ground stabilisation
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
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

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.
Symptoms that point to resin injection ground stabilisation
- Gaps opening beneath a ground-floor slab or path
- Floor slab dropping or hollow-sounding near one external wall
- Settlement after a drain leak has been found and repaired

Rules for resin injection ground stabilisation in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Frequently asked questions
How much should I budget for resin injection ground stabilisation in Perth?
Guide prices for resin injection ground stabilisation in Perth start from about £760 per metre of wall treated, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Perth?
Yes, Perth is covered, along with postcode districts PH1, PH2. We also cover nearby Blairgowrie and Crieff.
Why do houses in Perth and Kinross crack?
Perth and Kinross is largely Old Red Sandstone and Highland rock with glacial deposits and river alluvium along the Tay, which can be soft and flood-prone. Only an investigation can say why a particular building has moved.
Is the resin harmful to the ground or drains?
Once cured, the resin is inert in the ground. The practical risk is resin travelling into a damaged drain or service duct, which is why a CCTV drain survey comes first and any defects are repaired before injection. Services near the treated zone are located and protected.
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.
