Compound 3D drainage nets
3D composite drainage geonet Introduction
Three-dimensional composite drainage network is one three-dimension geonet
composited two needle-punched non-woven geotextiles. Offering completely
functions “filter-drainage-protection”. This kind of special three-dimensional
structure can make it bear higher compression loading and keep certain thickness
and same time offer excellent permeable performance.
3D composite drainage geonet Performance
1. Excellent drainage and sustain high compression loading
2. Highest tensile strength and shearing strength
3. Cut down ratio of geotextile into geonet and keep stable permeability in a long time
4. It can bear compression loading over 2000Kpa
5.Its compressive strength far exceeds general drainage geonet
3D composite drainage geonet Application
1,Landfill drainage;
2, Roadbed and road drainage;
3,Railway drainage, tunnel drainage, underground structure drainage.
4,The retaining back wall drainage,
5,gardens and sports grounds drainage.
