Drainage Boards are the single or multi-layered geosynthetic products which are often made with polypropylene PP or regenerated HDPE, some of them are covered with thermally bonded filament nonwoven geotextiles. Drainage Board products are widely used as drainage elements beneath traffic areas like frequently used pathways, car or truck usage, intensive green roofs or on vertical building components, etc. Drainage board products include drainage net, drainage cell, drainage sheet, HDPE grass paver and other customized drainage boards.

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. -
The three-dimensional composite drainage net is also called the geocomposite drainage net, which is made with double-layer geotextiles on one or both sides of the three-dimensional geonet by applying a special bonding processing technology. The three-dimensional composite drainage net combines the characteristics and functions of both geotextile and geonet. It has the charatertistics of filteration, drainage, ventilation, and enhanced protection. It is an ideal new type of drainage geotechnical material.

Sheet drain, also known as dimple drain sheets, is a three-dimensional plate with bumps or holes made of high-density polyethylene material through a special manufacturing process. The composite sheet drain can be connected to waterproof materials, concrete or wood with metal pins, construction adhesive or double-sided tape to form an efficient filtration and drainage system. Sheet drains are an ideal drainage solution for foundation walls, behind retaining walls and in green roof applications.
