Construction Laying Standards:

1. After the waterproofing layer and its protective layer are installed, proceed with the laying of the drainage board. The subgrade drainage slope must meet the requirement of 2‰ to 5‰.

2. Lay the drainage board cups with the open ends facing up, interlocking the teeth.

3. The geotextile is laid over the drainage board, with overlaps of 10-20cm to prevent mud and water from penetrating through the geotextile, clogging the drainage and water storage system, and causing inefficient drainage and reduced water storage capacity.

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

5. Cover with an appropriate thickness of planting soil.

6. Ensure proper protection of the drainage mat finish. After laying the drainage mat, it should not allow direct pushing of wheelbarrows and similar vehicles on the mat. Lay wooden boards or paths for transportation materials. Aim to fill the soil as the mat is laid.
