Sometimes unblocking a drain is not enough, the pipes may require relining. The lining systems we offer proven and established methods of placing a new pipe within an existing damaged pipe without excavation and with minimal disruption.

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 molded 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%.
pipe drain relining
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 design specifications required.

A special resin containing an activating catalyst is impregnated into the liner pipe prior to installation. lining is suitable for sewers and vertical rainwater down pipes etc, 75mm - 1000m dia. The liner is resistant to most aggressive chemicals and can withstand extremely high temperatures. A full technical specification is available upon request. drainunblocking.ie can offer a wide range of “No Dig” Solutions to our clients Such as ambient cure, hot cure, Part liners & High Strength UV Cure sewer lining.

Our Process:

pipe drain beforeCCTV inspection can locate a number of reasons that causes pipe failure including leaking and open joints, root intrusion and cracks
pipe drain pro 1A new Sewer liner is first impregnated with a special resin containing an activating catalyst before being winched through the damaged section
pipe drain pro 2An inflation hose is inverted into the new liner by air or water pressure
pipe drain pro 3This shapes the liner into the existing pipe and holds it in position while it cures. Hot water or steam can help control the curing process
pipe drain afterOnce 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
