Product Description

Drainage board have a flat back which is pressed against an underground structure such as a basement wall or subsurface footing. The pressure of backfilled soils holds the Drainage board in place. A filtration geotextile covers the drainage core. The geotextile allows unrestricted flow of moisture into the core while it restricts the passing of soil particles which could contaminate and clog the core. Since most of the soil exposed surface of a subsurface structure is covered with the Drainage board, hydrostatic pressure is virtually eliminated. Drainage board are very ligthweight, easy to handle and easy to install. They require no special equipment or skilled labor.


The major production facilities include three-layer construction film blow machine, calendering method geomembrane production line, the first company to introduce 8.5m width geotextile production linb, 7m width compound gemombrane production line, GCL production line as well as the patent technology first 3m width forming in only one time drain board production line to produce a variety og geosynthetics.

Our main products including geotextile, pvc geomembrane, HDPE geomembrane, composite geomembrane, compound geomembrane, Waterproof HDF Board, GCL, green roof drainage board, compound drainage net, geogrid, geonet, geocell,and so on. Our drainage board were exported to North America, Europe, East Aisa, South East Aisa, MIddle East and South America South Africa and many other countries.

Our drainage board has passed ISO9001:2000 international quality system certification, ISO14001:2004 Environment Management System Certification and GB/T28001:2001 Vocationl Healty and Safety System Certification. Besides, it has successfully passed on-side check on production license, and has gained National Industrial Production Protection Lincense and special water-proof qualification. At present, we have inport and export rights, and we are the member of Chinese Technical Association on Geosythetics and hss been recognized as a Provincial-level Enterprise Abiding by the Contract, keeping promise for several succsssive years. Besides, we arwarded the titles of Shandong Famous Brand.

Features & Application

Drainage board designed for vertical / horizontal applications at shallower depths where moderate compressive strength and flow capacity are adequate.
1. Water Drainage, Drainage board abon be used in combination with non woven to get rid of the rain immediately and effectively relieve the roof's pressure caused by the instanteous rainfall.
2. Ventilation,  Special design helps the plant layer to have good air-ventilation ability at the bottom, improves ventilating situation and ensures the oxygen demand for root.
3. Environment Protection, It is 100% recyclable, won't cause secondary pollution to the environment.
4. Safety & Light Weight, Plastic storage and drainage plate's light weight will not enhance load for roof structure. It required no cranes or lifting equipment.
5. Water Storage, Absorb and store redundant moisture leaking from the planting layer and supply needed moisture for the plant when the soil lacking of water to improve plant's drought-resistance ability.
6. Heat Insulation, The storage place for the Drainage Cell is at the bottom of the plant, helping the plant to stop from the sun direct illuminating and form a cool space, which can absorb heat from structure layer to form air troposphere.
7. Low Price & Quick Installation, Ultra-light weight, easy installation, quick construction, low construction cost and simple maintenance.
