Drain lining, a non-disruptive method used to repair the drain without excavation.
Some cracks and damages need not always require excavation. Our team will analyze such damages and use this highly effective drain lining method to fix those areas. We will insert a liner into the pipe and place it exactly on the damaged area using a CCTV camera. This patch is then pressed into the location using an inflated bladder. Once the patch cures, the drain is back to its normal functionality.
We use excavation as the last resort because we understand that our customers need their drainage problem to be resolved with minimum disruption. That’s why wherever possible we use no-dig technology or drain lining. Get in touch with us, we will explain to you everything about drain lining.
The new pipe material is similar to GRP (glass reinforced plastic) and in all cases will be superior in quality and strength to the pipe which it lines. The new pipe is moulded into the damaged pipe by an ingenious method called ‘inversion’ using water or air pressure, fitting it tightly against the wall of the existing pipe. When the inversion is complete the new pipe (which is originally flexible) is now rigid, resulting in a strong, tough pipe tightly fitted within the existing pipe with only a minimum loss of cross-section of approximately 6%.
The liner is manufactured from a special dense impermeable felt and is designed and tailored to fit exactly the internal dimension of the pipe to be refurbished. The thickness of the lining material can be varied according to the design specifications required.
We have a selection of three special resin systems – Polyester, Silicate and Epoxy with different curing times – suitable for various conditions and applications. These are impregnated into the liner prior to installation in the pipe.
The liner is suitable for sewers and vertical rainwater down pipes etc, 75mm – 300mmØ. It is resistant to the most aggressive chemicals and can withstand extremely high temperatures.
A special resin containing an activating catalyst is impregnated into the pipe liner prior to installation.

Once the pipe is cured, the inversion liner is removed leaving a strong and tough new pipe within the existing pipe. Any lateral pipes are reconnected by a remote-controlled robotic cutter.
