IMPREGLINER

THE LINER FOR TRENCHLESS SEWER REHABILITATION

The iMPREGLiner is one of the glass-fibre pipe liners that is used most frequently for trenchless sewer rehabilitation throughout the world. Well-known rehabilitation and civil engineering companies around the world trust in its high quality and rehabilitate more than 400 km of damaged pipes annually using iMPREGLiner.

Our users have two variants of the patented iMPREGLiner available, which is characteristic due to its simple and clean application on the job site as well as a long lifecycle of at least 50 years. The liner surface exhibits only minimal friction after rehabilitation, as a result of which the reduction in the size of the cross section is almost offset in full.

Our liner products cover all nominal diameters up to DN 1600. The iMPREGLiner is thus the only glass-fibre pipe liner approved by the DIBt, Berlin (German Institute for Construction Technology, Berlin) in the world that is made in series production in sizes larger than DN 1200.

All common profiles such as circular, egg-shaped, mouth or box, as well as special profiles, can be rehabilitated with the iMPREGLiner.

The impregnation is carried out at the factory with an ISO NPG polyester resin for municipal use or with a vinyl ester resin for aggressive waste water.

Dimension changes within a pipe can of course also be rehabilitated without problems. iMPREG can manufacture products specially for this, according to the customer’s requirements.

The iMPREGLiner is produced in accordance with monitored quality guidelines and is certified in accordance with ISO 9001:2008. As a result of the environmentally-friendly and energy-efficient production processes, the requirements of the energy management system in accordance with ISO 14001:2005 are met.
