The composite drainage network is a new type of drainage material

Subgrade Drainage: It is used at the bottom of highway and railway subgrades. It can effectively drain the accumulated water in the subgrade, lower the groundwater level, reduce the soaking and softening effects of water on the subgrade, improve the stability and strength of the subgrade, and extend the service life of the road.

Pavement Drainage: It can be installed within the pavement structure layer, such as between the base course and the surface course or inside the base course. It can quickly drain the rainwater that infiltrates into the pavement, prevent the damage to the pavement structure caused by accumulated water, and reduce the occurrence of pavement diseases such as mud pumping and potholes.

Dam Drainage: The composite drainage network is laid in the dam body or dam foundation of a dam. It can promptly drain the seepage water in the dam body and foundation, reduce the pore water pressure, enhance the stability of the dam, and prevent safety accidents caused by seepage failure of the dam.

Canal Drainage: It is used for seepage prevention and drainage of water conservancy canals. It can not only prevent the water in the canal from seeping into the surrounding soil but also drain the groundwater around the canal, protect the structural stability of the canal, and improve the water conveyance efficiency.

Landfill Sites: As an important part of the drainage system of a landfill site, it is laid at the bottom and on the slopes of the landfill. It can quickly divert and drain the landfill leachate, prevent the accumulation of leachate within the landfill, and reduce the risk of pollution to the surrounding soil and groundwater. At the same time, it also helps to maintain the stability of the landfill and prevent problems such as slope instability caused by excessive leachate.

Sewage Treatment Plants: In the sludge treatment area of a sewage treatment plant or in areas with a high groundwater level, the composite drainage network can be used for drainage and seepage prevention. It helps to control the groundwater level, prevent sewage from seeping, and protect the surrounding environment.

Basement Drainage: It is used for the floor and side walls of building basements. It can effectively drain the accumulated water around the basement, prevent groundwater from seeping into the basement, avoid the dampness and mildew of the basement, and protect the structure and internal facilities of the basement.

Roof Drainage: In the roof greening or flat roof drainage system, the composite drainage network can serve as a drainage layer, quickly draining the rainwater on the roof, reducing the load on the roof. At the same time, it provides good drainage conditions for plant growth and extends the service life of the roof waterproof layer.
