Which repair method suits a home in Llantrisant?
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 happens when we carry out resin injection ground stabilisation in Llantrisant?
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.

Resin injection ground stabilisation in Llantrisant: questions and answers
What is the price of resin injection ground stabilisation in Llantrisant?
Guide prices for resin injection ground stabilisation in Llantrisant start from about £735 per metre of wall treated, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Yes, Llantrisant is covered, along with postcode districts CF38, CF72. We also cover nearby Pontypridd and Tonypandy.
Does the ground around Llantrisant cause cracking?
Mid Glamorgan lies on the South Wales coalfield, with dense historic workings, spoil tips and steep valley sides. Landslip, retaining walls and mining legacy are all live issues in the valleys. 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.
Does resin injection work on clay soil?
Sometimes, but clay needs the most caution. If seasonal shrinkage from nearby trees is the cause, resin under the footing may not stop the drying below it. An engineer should look at the soil, the trees and the monitoring history before resin is chosen for a clay site.
