The plastic water storage and drainage board is made of high density polyethylene (HDPE) or polypropylene (PP) by heating, pressurizing and shaping. The storage and drainage board can create a drainage channel with a certain three-dimensional space supporting stiffness, and also can store water.

The plate itself has two kinds of comprehensive water storage, drainage function, characteristics of plate with high spatial stiffness, compressive strength is obviously superior to the similar products (through field test), able to withstand high compressive load more than 400Kpa, and can withstand extreme load conditions in the process of filling machinery rolling back in the planting roof.

Plastic water storage and drainage board has the functions of water drainage in the construction layer, the infiltration of water in the soil, and the permeable water of the storage and storage, which have the following advantages and disadvantages compared with the last generation of the drainage products.

1. North China is drought and less rain, the storage and drainage board can store water, which is beneficial to the growth of vegetation.

2. The storage bump drain side wall is thick, the compressive strength is larger, can reach more than 40T, is far greater than the plastic tab (high density polyethylene drainage plate, high impact polystyrene plastic drainage board), drainage mattress and other similar products (actual rolling experiment), can meet the construction requirements of filling and the back normal operation requirements;

3. The plastic water storage and drainage board supporting surface is relatively large, is not due to the overlying subsidence non-woven (below) blocking the drainage channel, not because of lack of tear in the dirt into non-woven tension and obstruction of drainage channels, drainage plate can complete retention of drainage space, completely avoid the plastic tabs for non-woven subsidence resulted in poor drainage the situation will not be due to poor drainage, causing the vegetation to wither and die.
