Resin injection ground stabilisation in Rhondda
A sunken floor slab or a settled corner in a Rhondda 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.

How we usually approach 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
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.
Ground and drain checks
Trial pits or probes confirm the soil profile, and a CCTV drain survey checks for leaks and for pipes in the injection zone. Damaged drains are repaired first, so resin is not lost into them or used to treat a cause that is still active.
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.
What to look for before calling about resin injection ground stabilisation
- A corner that has dropped but no longer moves with the seasons
- Settlement after a drain leak has been found and repaired
- Cracks over a section of wall built on loose fill

Questions about resin injection ground stabilisation in Rhondda
How much should I budget for resin injection ground stabilisation in Rhondda?
Guide prices for resin injection ground stabilisation in Rhondda 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.
Can you survey a property in Rhondda?
We do. Rhondda and the surrounding area are covered, including nearby Tonypandy and Mountain Ash. A free initial assessment from your photos is the first step.
Why do houses in Mid Glamorgan crack?
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.
Can resin injection lift my house back to level?
It can produce small, controlled lifts, but it is not a way to jack a house back to its original position. The main aim is to stabilise the ground. Laser levels are watched throughout so injection stops before the lift strains the walls or opens new cracks.
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.
