Trenchless Technology of Pipeline Rehabilitation

SAERTEX Liner is a flexible GRP liner made of fiberglass, impregnated with a special resin. The resin is cured with UV lamps.

SAERTEX-LINER

Use in very complex cases

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.

Slight reduction in pipe cross-section

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.

Immediate Tightness Testing

The inner film of SAERTEX-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.
