Product Description

Product Description

The water storage and drainage board is made of polyethylene plastic injection molding. It is a new type of drainage material that integrates drainage and water storage functions. It also has multiple functions such as water storage, drainage, ventilation, insulation, and root resistance (preventing plant roots from damaging concrete structures). When combined with geotextiles, it can prevent fine particle matrix from blocking water storage tanks and drainage channels, maintain smooth drainage and air circulation, and form a complete and new type of water storage and drainage system, which is widely used in urban landscaping projects.

 

1. Convenient construction, easy maintenance, and economical.

2. Strong load resistance and durability.

3. Can ensure that excess water is quickly drained.

4. The water storage part can store some of the water.

5. Can provide sufficient water and oxygen for plant growth.

6. Lightweight and with strong roof insulation function.

Installation Instructions

After the construction of the waterproof layer and its protective layer is completed, start laying the drainage board. Require the slope of grassroots drainage to meet a range of 2 ‰ to 5 ‰;
2. Lay the drainage board with the cup shaped mouth facing upwards and the teeth interlocked;
3. Cover the drainage board with geotextile, overlapping 10-20cm to prevent mud and water from passing through the geotextile, clogging 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. It is necessary to ensure the protection of finished drainage boards. After the installation of the drainage board, it should not be allowed to directly push hand carts on the drainage board. When transporting materials, wooden boards and horse paths should be laid. Ensure that the soil is filled as soon as it is laid.
