GRP Slip Lining:
- The GRP slip lining system consists of one or more pieces or multi sectional glass fiber reinforced plastic (GRP) panels manufactured from a selection of thermosetting resins and reinforced with glass fiber chopped strand mat. A glass surfacing tissue liner layer provides additional corrosion protection and abrasion resistance.
- The main structure of the liner and make-up of the liner wall incorporates a corrosion barrier on the inside surface followed by resin to give a resin to glass ration of approximately 2:5:1
In procedures utilizing GRP liners, the annulus between the wall of the host pipe and the liners is filled with a cementious grout. The high strength of the grout and the strength and durability of the GRP lining ensures a long life for composite units.
