GRP Liner is a flexible GRP liner made of fiberglass, impregnated with a special resin. The resin is cured with UV lamps.
Higher characteristics of the modulus of elasticity and tensile strength make it possible to use the liner in complex cases. This allows repairing worn-out pipes in non-pressure pipelines.
Reduction factor A and high modulus of elasticity allows the use of a thinner wall thickness, which gives an insignificant decrease in the cross-section of the pipe under extreme static loads.
The inner film of GRP liner is removed after curing, this means that the tightness of the pipe can be checked immediately. All the tests carried out by the research institutes showed an excellent result.
