Product Introduction:

　　The drainage board is divided into two series: coiled material and sheet material. In terms of shape, a special process is used to press the plastic board out of a closed convex cylindrical shell, forming a concave convex membrane. The shell is continuous, with three-dimensional space and a certain support height. During the processing and production of the edges, butyl rubber strips are thermally adhered, and the top of the shell is covered with a geotextile filter layer, which is used for products such as seepage, drainage, and water storage.

　　Performance characteristics:

　　1. Convenient construction, easy maintenance, and economical.

　　2. Strong load resistance and durability.

　　3. Can ensure the rapid discharge of excess water.

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

　　5. It can provide sufficient water and oxygen for plant growth.

　　6. Lightweight and with strong roof insulation function.

　　Purpose:

　　1. Greening engineering: garage roof greening, roof garden, vertical greening, sloping roof greening, football field, golf course.

　　2. Municipal engineering: airports, road embankments, subways, tunnels, and landfills.

　　3. Construction engineering: upper or lower layers of building foundations, indoor and outdoor walls and baseplates in the basement, as well as top plates, roof anti-seepage and insulation layers.

　　4. Hydraulic engineering: anti seepage of reservoirs, reservoirs, and artificial lakes.

　　5. Transportation engineering: highways, railway embankments, embankments, and slope protection layers.

　　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.
