These reinforcing monofilaments carry in the Sealing membrane does not contribute significantly to the reference force at low strains. However, they have a significantly higher maximum tensile force extension than that Glass mat; thus the areal connection of the geomembrane also becomes guaranteed in the event of deformations that can lead to breakage of the glass fleece.
