Adopting brand-new water drainage concept, E’DRAIN capillary drainage band, board and pipe products simulate natural ecological mechanism, cleverly use four natural phenomena —— “capillary force, siphone force, water surface tension and gravity”, it works upon principle of initiative water absorption and discharge, and it has special function with effectively prevent clogging and silting-up.

Through years of practical application, E’DRAIN capillary drainage product is made of weather-proof PVC flexible materials with ductility, its drain slot and structure is formed by extrusion process, dimension is as following: 

1. Slots are set on 2mm thick plastic PVC sheet, there is one 1mm diameter  capillary pore every 1.5mm along transverse direction, and capillary pores extend lengthways along the sheet.

2.Split a 0.2~0.3mm-width water suction groove lengthways along the extending pores, making it to form“Ω”structure.
The principle of capillary drainage materials preventing drainage system from clogging is mainly by making use of two natural phenomena, gravity and capillary suction, its structural design with continuous groove and  “Ω”structure ensures no clogging.

Takes specific HDPE resin and masterbatch as raw materials, by process of extruding, setting and heat-bonding with PP or PET nonwoven geotextile to form the E’DRAIN geocomposite drainage product. It has characteristics of excellent transmissivity, compressive strength and durability, making it an ideal drainage material.
