Several Basic Steps for Drainage Board Installation: Manager Feng 138/538/62645

The required gradient for the grassroots drainage slope should be between 2‰ and 5%, ensuring a certain slope but not excessively steep.

2. Lay the drainage board with the cup-shaped mouth facing up, and the teeth will interlock automatically.

3. After the drainage board is laid, cover it with geotextile. Offer HDPE wholesale root barrier drainage boards. The geotextiles overlap by 10 to 20 cm to prevent mud and water from penetrating through, thus avoiding clogging the drainage and retention system, which could lead to poor drainage and reduced water retention.
