Polieco - Model ECOPAL NO LOSS -Polyethylene Corrugated Pipe

The ECOPAL pipe is a double walled co-extruded corrugated pipe, smooth on the inside in grey and corrugated on the outside in black, for non-pressure underground drain pipes. The NO LOSS gasket is added to the normal ECOPAL system, consisting of an EPDM seal and coupler or socket. It is placed in the groove between the second and third corrugations of the pipe to prevent liquid infiltrations or leaks at the coupling points.

The NO LOSS gasket is a water-stop expanding seal that expands on contact with water. The Polieco NO LOSS water-stop expanding seal consists of synthetic rubber added with polymers, packed as preformed tape.

This particular system consisting of a coupling with water-stop expanding seal is used where a traditional coupling system may not be adequate due to settling of the surrounding soil.
