Specifications

Geocomposite for planar drainage consisting of extruded polypropylene monofilaments heat-welded to each other at contact points forming a three-dimensional matrix with parallel longitudinal channels, thermally coupled to (3 different versions):
a. two filtering nonwoven geotextiles (range Terradrain W1..1)
b. one filtering nonwoven geotextile (range Terradrain W1..0)
c. with one filtering nonwoven geotextile and with one polymeric reinforced membrane (range Terradrain W1..M).
The geocomposite will have the following characteristics:
• Thickness at 2 kPa equal to … mm
• Tensile strength MD/CD equal to …/… kN/m
• In-plane flow capacity of … l/m.s (vertical and under 20 kPa load) and … l/m.s (vertical and under 100 kPa load)
