Resin injection ground stabilisation in County Armagh
Across County Armagh, requests for resin injection ground stabilisation usually begin with a crack someone has noticed getting wider. Most of County Armagh is on firmer ground than the clay belts of the south-east. A repair only lasts if the reason for the movement has stopped.

How do local ground conditions affect resin injection ground stabilisation in County Armagh?
County Armagh has glacial drumlin till over older rock, with soft ground and peat near Lough Neagh.
Ground movement here is more often linked to soils, drains and trees than to mining. Across County Armagh, most homes are Georgian houses in Armagh, brick terraces in Portadown and Lurgan, and post-war estates.
What to expect when we carry out resin injection ground stabilisation
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.
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
- Cracks over a section of wall built on loose fill
- Settlement after a drain leak has been found and repaired
- Gaps opening beneath a ground-floor slab or path
- Floor slab dropping or hollow-sounding near one external wall

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 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.

Your resin injection ground stabilisation questions
Does the ground around Craigavon cause cracking?
County Armagh has glacial drumlin till over older rock, with soft ground and peat near Lough Neagh. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will resin injection ground stabilisation cost in County Armagh?
On Northern Ireland rates, resin injection ground stabilisation starts from about £705 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.
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.
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.
