The combination of drainage board and geotextile can drain rainwater quickly

Advantages of drainage board:

1. High strength-and small deformation;

2. corrosion resistance-and long life: drained boards are protected by plastic. They are assisted by various auxiliaries, which have anti-aging-and oxidation functions,-and can be corroded by harsh environment such as acid, alkali-and salt.

3. The construction is convenient, fast, short cycle-and low cost: the drainage board is easy to lay, lap-and locate, flat, avoiding the stack-and interpenetration, which can effectively shorten the project cycle-and save 10% - 50% of the project cost.

Characteristic performance of drainage board:

Drainage performance: the combination of drainage board-and geotextile can quickly discharge rainwater-and effectively relieve the pressure caused by instantaneous concentrated rainfall on the roof.

Water storage performance: absorb-and store the excess water exuded from the planting layer,-and supplement plant water when the soil is short of water, so as to improve the drought resistance ability of plants.

Water permeability: the special design makes the bottom of the planting layer have good air mobility, improves the ventilation of the substrate,-and ensures the oxygen demand of the root system.

Heat insulation performance: the water storage in the water storage-and drainage board is located at the bottom of the planting layer-and is not directly exposed to the sun, forming a cool space, which can absorb the heat conducted by the structural layer-and form an air troposphere.
