3D drainage geocomposite consists of a layer of HDPE made geonet in the middle, and PET or PP nonwoven on the outside of geonet.
It's substitute for traditional drainage material like sand and stone. The drainage capacity is equivalent or even bigger than that of 1m thick rubble. It has excellent creep performance, long term anti-corrosion to chemicals, good anti-clogging. It can be used in harsh environment.Good drainage (equivalent to 1m thick rubble)
High tensile strength
Reduce possibility for geotextile to get into core, thus keep steady permeability in long time
Can bear high pressure load under long time (approx...3000Ka compression load)
Anti-corrosion, anti-alkaline and acid, long life
Easy to install, can shorten project period and reduce cost
