Resin injection ground stabilisation in Coleraine
For a Coleraine 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.

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
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
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.
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.
Rules for resin injection ground stabilisation in Northern Ireland
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.
Questions about resin injection ground stabilisation in Coleraine
What is the price of resin injection ground stabilisation in Coleraine?
Guide prices for resin injection ground stabilisation in Coleraine start from about £705 per metre of wall treated, including VAT, on Northern Ireland 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 Coleraine?
Yes, Coleraine is covered, along with postcode districts BT52. We also cover nearby Ballymoney and Limavady.
Does the ground around Coleraine cause cracking?
County Londonderry has basalt, older hard rock and glacial deposits, with soft river ground along the Foyle and Bann. Only an investigation can say why a particular building has moved.
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 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.
