Application and function of 20mm water storage and drainage board:
1
The water storage and drainage board is made of high-density polyethylene (HDPE), which is formed by heating, pressing and shaping
It is a light board that can not only create a drainage channel with three-dimensional space support stiffness, but also store water
This kind of plate has two comprehensive functions of water storage and drainage
The plate has the characteristics of high spatial stiffness, and its compression resistance is obviously better than that of similar products (which can be verified by field test)
It can bear the high compression load of more than 400kPa and the load of mechanical rolling in the process of planting roof backfill

2
The water storage and drainage board forms a drainage layer, which realizes the integration of water storage and drainage of the drainage board
At the same time of drainage, it has the dual functions of storage and drainage, especially in terms of water storage
According to the rainfall, it can timely eliminate the waterlogging caused by a large amount of precipitation
At the same time, it can also store the water required for plant growth, with a water storage capacity of 10-90%, so as to ensure that the water stored in drought can evaporate to the planting layer and supply water to the plants above
