2D Composite Drainage Network
2D composite drainage network is an excellent choice for drainage applications requiring filtration to keep silt and soil particles from clogging flow. This non-woven geotextile has improved friction properties that facilitate its bonding to a geonet core. As a synthetic drainage media, our geocomposite is designed to replace one to three feet of traditional aggregate while providing drainage under various conditions, site loads, and gradients.
2D Composite Drainage Network Introduction
Composite drainage network is an excellent choice for drainage applications requiring filtration to keep silt and soil particles from clogging flow. This non-woven geotextile has improved friction properties that facilitate its bonding to a geonet core. As a synthetic drainage media, our 2D composite drainage network is designed to replace one to three feet of traditional aggregate while providing drainage under various conditions, site loads, and gradients.
The geonet core has two structures. Here, this structure is bi-axial structure as showed the picture below:
Directly laying on the ground, instead of the foundation which can dewatering, it can also make the concrete hydrated more evenly and extend the working life of road.
Laying composite drainage network will relieve the influence of frost heaven weather in the cold climate, which can be explained using the picture below:
♦ Good bearing of long-term high-pressured load.
♦ High tensile strength and shear strength.
♦ Reduce the chance of geotextile embedded network core to protect the long-term stability of the hydraulic conductivity.
♦ Excellent chemical resistance characteristics.
The application example of 2D composite drainage network for the protection of cover soil in a human made structure:
The application example below is the geocomposite for the protection in slopes of embankments:
