　　Construction laying specifications:

　　After the construction of the waterproof layer and its protective layer is completed, start laying the drainage board. Require a drainage slope of 2 ‰ to 5 ‰ at the grassroots level;

　　2. Pave the drainage board with the cup shaped mouth facing upwards and the perforations interlocked;

　　3. Cover the drainage board with geotextile, overlapping each other by 10-20cm, to prevent mud and water from passing through the geotextile, blocking the water storage and drainage system, causing poor drainage and reduced water storage capacity;

　　4. Lay 10-20mm medium coarse sand on the geotextile to form a permeable filter layer, which can prevent the loss of planting soil;

　　5. Cover with appropriate thickness of planting soil.

　　6. Do a good job in protecting the finished drainage board. After the drainage board is installed, it should not be allowed to directly push carts or other materials on the drainage board. When transporting materials, wooden boards and packways should be laid. Ensure that the soil is filled as it is laid.
