Drainage Maintenance
Drain Lining The drain relining system is a proven and established method of placing a new pipe within an existing pipe with no excavation and with minimal disruption. the new pipe material is similar to GRP (glass re-inforced plastic) and in all cases will be superior in quality and strength to the pipe which it lines. the new pipe is moldered into the damaged pipe by an ingenious method called "inversion" using 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 the minimum loss of cross section. The drain relining system 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 drain relining material can be varied according to the design specification required. A special resin containing an activating catalyst and hardener is impregnated into the drain relining tube prior to installation. Drain relying is suitable for drains, sewers and vertical down pipes. It can also be used to seal tanks, chambers and manholes to name but a few. |
