SKZ Develops New Geomembrane with Integrated Drainage Channels
A new, patented process describes the integral manufacturing of a geosynthetic drainage sheet (GDS) from a single plate-shaped base body. In the simplest case, grooves (MD “machine direction”) and counter-grooves (CMD “cross-machine direction”) are introduced into an extruded, plate-shaped base body with the aid of embossing rollers. These grooves are formed by material displacement, which leads to opening passages at the crossing points of the grooves and counter-grooves.
