Long lasting→resistant to acids and alkalis
High load capacity, high tensile strength→due to good elasticity it takes spot loads well
Excellent permeable capacity
Simple installation, few tools are needed, easy to cut and drill
The VL-type geotextile has several functions on green roofs, but filtration and mechanical protection makes up approx. 80 % of their application
VLF geotextile is a filter layer with very low clogging indicator, allowing the water to flow away freely from the growing medium, preventing particles wash out thus assuring the flow of redundant water into the drainage system
VLU products protect the roof insulation boards against damage during the installtion and future maintenance work serving as a protecting layer
The VLS materials are suitable to absorb larger quanties of water due to it‘s mixed fibers, thus we recommend their use especially when higher water storing capacity is required due to the climate or the projects‘ characteristics demand it
The VL-product family is a geotextile made of synthetic material suitable for fabric
formation, made by needle-felting procedure and upon the mechanical features, it is excellent for separating, filering and water retaining tasks on green roofs.
