Trolining GmbH

Trolining GmbH, a medium-sized company located in Troisdorf / Germany, is recognized as a leader worldwide in the field of trenchless pipe rehabilitation.

The TROLINING System is based on various HDPE liner components which can be combined in a wide range of alternative configurations. The heart of the system is the Troliner with its V-shaped embedment studs. The annular void created by the studs is filled with TROLINING Injektor, a specially engineered injection grout. This high-strength grout fixes the Troliner permanently in place and provides the load-bearing shell of the system. The system is suitable for lining of pipes ranging from 250 mm to 2000 mm (or 10 to 80 inch) I.D..
