Low price wholesale geonet or geocomposite filtration network composite drainage network
Customized all size of Geosynthetics
Welcome to YINGFAN
Professional Geosynthetics manufacture
Product Description
Composite Drainage Network is a new type of dewatering geotechnical material, which the raw material is HDPE and manufactured via particular extrusion forming technique. It has three levels, the inner fillet has strong rigidity, arrange longitudinal to form dewatering channel, the upper and bottom fillet form support to avoid geotextile inserting into dewatering channel, that means even if under high load it can also keep good dewatering property. It is the best dewatering material currently who has below function:" filter -- dewatering -- ventilate -- protect".
