A glass fiber reinforced liner is impregnated with resin, then pulled into the pipe to be rehabilitated via existing shafts. The liner is then closed, put under pressure and cured with UV light. After curing, the system provides a structural liner which is comparable to a new pipe.
Glass Reinforced Plastic (GRP) is a composite material that combines a high chemical resistance with extreme tensile strength and exceptional durability. GRP consists of glass fibres embedded in polyester or vinyl ester resin to reinforce it in an orientation tailored to a specific application.
The great stability under load and durability of the material combined with the glass fibres permanent resistant to chemicals and corrosion make it ideal for use in pipe renovation.
