The 3D composite drainage network is made of high-density polyethylene (HDPE). The ribs are extruded through a special die. The three ribs are arranged according to a certain distance and angle to form a 3D spatial structure with drainage guide channel. The middle rib has greater rigidity, forming a rectangular drainage channel. The results show that the three-layer ribs of the drainage network have high longitudinal and transverse tensile strength and compressive strength,the drainage guide channel formed between the three-layer ribs is not easy to deform under high load, which can prevent the geotextile from embedding into the core of the geonet and ensure smooth drainage. The 3D geotechnical drainage network has high strength and high drainage type according to the requirements.

Dimpled drainage board is also called “Building Sandwich Plastic Board”. It is made of HDPE or PVC plate through stamping, which is finally a plate with conical dimples.

Composite drainage Plate (also known as 3D composite drainage network, drainage grid) is a new type of drainage geotechnical material. It is made of high-density polyethylene (HDPE) and processed by a special extrusion process, with a three-layer special structure.

HDPE Plastic Store-Drainage board is a kind of new-style material, which is molded by HDPE material and has high tensile strength, not easily deformation. It has the features of store water and drainage water and is very popular in some projects.

The grass lattice is made of modified high molecular weight HDPE, which is environmental and 100% recyclable; it is perfect in combination of turf and car parking, which is pressure resistant, wear resistant, impact resistant, ageing resistant and corrosion resistant. It improves level of landscape and saves the cost of construction. It’s unique flat lap joint saves labor and time, and the expansion joints can be adjusted.

3D geomat is a new type of earthwork synthetic material which is suitable for soil and water conservation. It can effectively prevent soil erosion and increase the green area and improve the ecological environment.
