Tr-dimension Composite Geonet for DrainageTr-dimension Composite Geonet for Drainage
Product Description
Tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides.It is used to replace a sand or gravel subsurface drainage system.This is accomplished by heat laminating a needle punched nonwoven geotextile to both side tp prevent soil particles from clogging the drainage core.Geotextiles are also laminated to geonet cores when there is a need to increase frictional characteristics with another geosynthetic type.
Three-dimensional network of drainage features
1.Excellent drainage function,can bear long time high press load
2.High tensile and shear strength
3.Reduce the rate geotextile embedding into the core of geonet,can protect long time stable water conductivity
4.Tri-dimension composite geonet for drainage can bear more than kpa compression load
5.Its anti-compression capacity is much larger than common geonet for drainage
Typical Applications
Landfill drainage;roadbed and road drainage;railway drainage,tunnel drainage,underground structure drainage,the retaining back wall drainage,gardens and sports grounds drainage.
