Resin Injection Drain Repairs in Irlam , Salford

With the high water table near the Leeds and Liverpool Canal in Clayton-Le-Moors, damaged drains often suffer from heavy water infiltration pouring in from the surrounding soil. We push an inflatable mechanical packer to the exact fracture and inject a specialist polyurethane resin straight through the pipe wall into the surrounding ground. The resin reacts with the moisture, expands rapidly, and creates a dense, watertight seal outside the pipe to cut off the leak completely.

A standard cured-in-place sleeve only lines the inside barrel of the pipe, leaving any washed-out soil or voids on the outside untouched. Resin injection actually forces expanding structural resin through the fractures into the surrounding sub-base to fill hollows and stabilise shifting ground. It strengthens the ground supporting the pipe while sealing the leak, giving you structural stability without having to dig up your property.

Polyurethane injection resins react and cure quickly, setting hard within thirty to forty-five minutes of application. Once the resin sets, we run a CCTV camera down the line to confirm the pipe bore is smooth and water flows freely, and then the job is finished. You can run taps, take showers, and flush toilets as soon as we pack our kit away.

Yes, this is one of the biggest advantages of resin injection over traditional excavation for Clayton-Le-Moors properties. The liquid resin seeks out empty cavities beneath your tarmac or block paving, expanding under pressure to lock loose aggregate together into a solid, load-bearing mass. This stops driveways and paths from dipping or cracking above the leaking drain run without bringing a mini-digger onto your front garden.

We feed an injection packer fitted with a live CCTV camera through an existing manhole or access point directly to the damaged section. Once the packer sits squarely over the break, we inflate it to seal off the repair zone and pump the resin through calibrated injection ports under pressure. We watch the entire repair on a monitor to make sure the resin fills the void fully before deflating the packer and retrieving it.

Yes, it works exceptionally well on older clay pipes where the original cement mortar joints have washed away or ground shifts have fractured the pipe collars. The resin forms a tight mechanical bond with rough clayware and expands into open joint gaps that standard patch repairs might fail to seal properly. It creates a flexible, long-lasting barrier that flexes naturally with local East Lancashire clay soil movements.
