Predl Systems North America Inc. (Predl Systems) is affiliated with PREDL® (www.predl.eu), one of the largest developers and manufacturers of manhole liners in Europe. Predl Systems locally manufactures custom FRP (Fiberglass Reinforced Plastic) manhole base liners and distributes complete Predl PP (Polypropylene) manhole liners for the USA and Canadian markets. In addition, Predl Systems designs and manufactures a line of off-the-shelf products for the sanitary sewer and wastewater industry, which may be used with or without other Predl technologies.

Predl EU and affiliates have installed over 1.5 million manhole base liners worldwide. Predl Systems, located in Vancouver, BC, has operated in North America since 1988 and have installed nearly 50,000 base liners. Pierce County in WA State has specified and sole-sourced Predl Base Liners exclusively since 1989 and have installed over 10,000.

Professional due diligence is conducted directly between Predl Systems and the municipalities’ engineering and/or planning departments. Predl Systems resources include professional engineering and civil design staff services who can document recommended solutions to address manhole and collection system challenges. Predl Systems will provide all required custom and standard engineering PDF and DWG file format drawings.

After a municipality has specified Predl Base Liners or complete Liner Systems as the sole source manhole liner requirement a contractor will bid for the construction project. The local Predl Certified Precaster will provide the contractor with all necessary costs to supply the finished custom or standard lined concrete manhole structure accurately installed as specified. The winning contractor submits the order for the Predl lined manhole structure to the local certified precaster who in turn purchases the specified liner(s) from Predl Systems.
