Water main and sewage drain repairs

Grit Ninja

Within pipe diameters up to 600mm, we commonly use Polyester resin based felt liners. Runs of up to 80m in length can be lined for 100 and 150mm diameter pipework, 50m runs for 225, 300mm diameters and 30m long runs for the larger diameters. This liner is temperature sensitive and more suited for use in straight sections.

The liner is placed in the host pipe impregnated with resin. An Air Inversion Chamber is then used to inflate the line hose into position; it’s then left to cure. This system is suitable in most sewer refurbishment situations with wall thickness from 2mm to 9mm for structural applications. Robotic lateral cutters are used to open blind connections where applicable.

In the event a defective host pipe deviates, we use an Epoxy Flexi liner which is more suited to the job. The use of a woven polypropylene sock slightly elasticised is impregnated with epoxy resin is blown by air down the pipe under approx. 1 bar of pressure.

 

The liner traverses round bends following the precise contours of the host pipe. Once in position, the resin sets, bonding the liner to the pipe walls. Fractures and open joints are sealed increasing pipe strength and eliminating the chances of smells from leaving cracked pipes and stopping water egress into the surrounding ground.
