G.S.E. Sheet Drain is a composite drainage system consisting of a three-dimensional, crush resistant, core and a non woven, needle punched geotextile. The product is used in a similar manner to the fabrinet drainage core described below. The difference between the two is the structure of the core.
The core of G.S.E. Sheet Drain is comprised of a solid sheet of density polyethylene with moulded studs to provide the core space. Thus, the product has a water proof side on the back as opposed to the open net of fabrinet. By overlapping this core a water resistant backing is achieved. Flow rates are also greater with the G.S.E. Sheet Drain.
