FOLIENMATERIAL ZUM KONTROLLIERBAR DICHTEN TRENNEN DER AUF SEINEN BEIDEN SEITEN BEFINDLICHEN BEREICHE

摘要

A flexible foil material for controllable leakproof separation of the areas located on both of its sides, for example a drainage separating wall. In the intermediate area between two closed foils a two-dimensionally connected distance-piece is envisaged which forms an open flow cross-section parallel to the length of the foil, so that harmful matter which enters at any point in the intermediate area is diverted to another point and thus can be recognized.
