epros®Drain Liner Types

The epros®DrainLining method is a technology for application in trenchless ("no-dig") pipe and sewer renovation. According to this method, a flexible tube (=liner), which is made of non-corrosive synthetic and/or glass fibres and coated with a foil on the outside, is wetted from the inside with thermosetting resins (epoxy resins) and inverted through a manhole or pipe opening into the host pipe.

Trelleborg Pipe Seals provides all kind of carrier material for the rehabilitation and repair of main lines, laterals, lateral connections, horizontal and vertical pipes with bends and change in diameter.

epros®DrainHybridLiner

If you are looking for a competitive alternative to the UV curing method that requires a high investment into technical equipment the epros®DrainHybridLiner is the solution that meets with less demands.

Due to the high proportion of ECR glass fiber in its composition, this liner is able to deliver outstanding mechanical properties when paired with Trelleborg’s EPROPOX resins. The high flexural modulus of the resulting cured liner results in a wall thickness of only 4.5 mm [0.18”] and saves a considerable amount of resin. This pays off when undertaking bigger pipe rehabilitation projects.
