- PRODUCT DESCRIPTION
Composite drainage network is a new type drainage geotextile with HDPE as its raw material. It is formed after special extrusion forming process and has special structure with three layers. The middle steel bars are rigid and are arranged longitudinally to form drainage channel. The support formed by steel bars arranged crosswise can prevent geotextile from inserting drainage channel. The drainage channel also can keep good drainage performance even if under high load.
Characteristics of Three-dimensional Composite Drainage Network:
It has strong drainage capacity and is able to withstand long-term high-pressure load
Extremely high extension strength and shear strength
It can prevent geotextile from inserting network core and protect long-term and stable hydraulic conductivity
Three-dimensional composite drainage network can bear the compression load greater than 2000kpaKeywords:
