Drainage cell is made from HDPE or PP by means of heating, pressurization and molding by into a unique shape then wrapped in a filtration geotextile, which can not only create a drainage channel with certain stereo space support stiffness, but also is able to impound water. The filtration geotextile generally covers the drainage core allows unrestricted flow of moisture into the core while it restricts the passing of soil particles which may clog the core. The drainage cell is characterized with high compression strength, lightweight, corrosion protection, acid and alkali resistance, resistance to plant roots puncture, etc. It is the most advanced and versatile geo-composite product suitable for all your horizontal and vertical drainage applications such as garden, landscape, terraces, pavers, subterranean building, etc.
