green roof waterproof protection drainage board/cell/sheet Feature:

1.Water Drainage: Drainage plate can be used in combination with non-woven to get rid of the rain immediately and effectively relieve the roof’s pressure caused by the instantaneous rainfall.
2. Water Drainage :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.
3.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.

4.Heat Insulation: The storage place for the drainage plate 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.
5.Safety: Plastic storage and drainage plate‘s light weight will not enhance load for roof structure.
6.Environment: it is 100% recycling, won't cause secondary pollution to the environment.
7. Bearing Performance :Bearing strength for storage-drainage plate can reach 80 ton per square as the highest, suitable for all kinds of landscape on the top.
8.Low Price: ultra-light weight, easy installation, quick construction, low construction cost and simple maintenance.
