Resin injection ground stabilisation in West Glamorgan
Across West Glamorgan, requests for resin injection ground stabilisation usually begin with a crack someone has noticed getting wider. West Glamorgan has a mix of ground, with clay in some places and firmer rock in others. A repair only lasts if the reason for the movement has stopped.

What is the ground like in West Glamorgan?
Swansea and Neath Port Talbot lie on the South Wales coalfield, with historic workings, tips and steep valley sides, and softer estuarine ground around the docks.
Historic coal workings are recorded beneath parts of West Glamorgan, and a coal mining search is worth checking where movement is unexplained. Across West Glamorgan, most homes are hillside terraces, Victorian villas in Swansea and post-war estates.
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.
Is it time for resin injection ground stabilisation? Common signs
- Floor slab dropping or hollow-sounding near one external wall
- Cracks over a section of wall built on loose fill
- Gaps opening beneath a ground-floor slab or path
- Sinking that trial pits trace to loose or washed-out soil

Repair options we may recommend
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
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
Do you need approval for resin injection ground stabilisation in Wales?
In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.

Your resin injection ground stabilisation questions
Is the ground in West Glamorgan prone to subsidence?
Swansea and Neath Port Talbot lie on the South Wales coalfield, with historic workings, tips and steep valley sides, and softer estuarine ground around the docks. Historic coal workings are recorded beneath parts of West Glamorgan, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.
How much will resin injection ground stabilisation cost in West Glamorgan?
On Wales rates, resin injection ground stabilisation starts from about £735 per metre of wall treated, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Is resin injection better than underpinning?
It is better for some jobs and unsuitable for others. Resin is quicker and less disruptive where the problem is loose or washed-out soil close to the footing. Underpinning or mini-piles are usually the safer choice for deep soft ground or clay dried by trees that cannot be removed.
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.
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.
