Geocomposite drainage is a drainage system consisting of three-dimensioanal high-density polyethylene
geonet, with high permeability, compressive strength and tensile strength, combined on one or both sides with
a nonwoven polypropylene geotextile.
1. Three functions in one unit: filtration, drainage and protection.
2. The installation is simple and rapid comparing to traditional sand grains and gravel layer.
3. Cost-effective substitute for traditional drainage system provide savings on materials, transportation and in-
4. Chemically resistant construcion provide long life in harsh environments.
Specifications and technical parameters:
Drainage network core
Heavier grades of geotextiles can be bonded to geonet on request
In the railway, highway and other transportation infrastructure, drainage system safety and the service life
of the project and its have inseparable relationship, in which the geotextile material is an important part
of drainage system, the drainage effect of 3D composite drainage net is particularly notable. mainly
used for tunnels, municipal engineering, reservoir, revetment in drainage engineering.
