Products and services

Primus Line® system, an innovative relining solution for the trenchless rehabilitation of pressure pipes for different applications such as water, gas and oil. The system consists of a flexible Kevlar® reinforced liner and specially developed end fittings. Clients benefit from long insertion lengths of up to 2,500 m in one single step and the product’s ability to traverse bends of up to 45 degree. Primus Line® is not bonded to the host pipe and is self-supporting. An annulus remains between Primus Line® and the host pipe.
Small construction pits, short rehabilitation times and the low level of impact on the environment, make Primus Line® the ideal technology for the rehabilitation of defective lines in sensitive environments.
