How we usually approach resin injection ground stabilisation

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 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.
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.

Rules for resin injection ground stabilisation in England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Questions about resin injection ground stabilisation in Brentwood

How much should I budget for resin injection ground stabilisation in Brentwood?

Guide prices for resin injection ground stabilisation in Brentwood start from about £840 per metre of wall treated, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Essex crack?

London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk. Only an investigation can say why a particular building has moved.

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.

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.
