Tr-dimension Composite Geonet for Drainage
Description
Tr-dimension composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides.it has the property of geotextile(filtration function ) and geonet (drainage and protection ) and provide a function system"filtration-drainage-protection".the core of net with its unique tri-dimension structure can bear higher compressing load in construction and remain the certain
thickness,provide good water conductivity.
Application
1pass through strict quaility control production line and have stable performance and good property of conducting water .
2.light ,no more extral load ,anti-pill,anti-compress,anti-impact and can prevent geomembrane from damage .
Width 4-6m
Specification membrane thickness 0.2mm-0.8mm; protective geotextile 100g/m2-800g/m2 (produced by our factory, conforming to the related national standard).
