Drainage Nets, also known as Composite Geonets, are a kind of three-dimensional drainage geosynthetic products which are made of polypropylene or HDPE and are covered with single or double-sided heat-bonded nonwoven geotextiles on both of the two sides or just one single side.
The geonet has high drainage performance, as it is made of high-quality polyethylene resin with the anti-UV and anti-oxidant extruding process. Tinhy’s Drainage Nets perform better than other types of draining gravels. The three-dimensional composite Drainage Nets are definitely a sort of suitable materials which combine the traits and features of Geotextiles and Geonets together and take a good effect on anti-filtration, drainage, air permeability, and protection.
Three dimensional Drainage Nets can be applied beneath the foundation to stop the sand and grit from penetrating into Geonets and effectively realize the function of drainage and reinforcement. Drainage Nets are widely applied in railways, tunnels, expressways, municipal infrastructures, tailing dams, slope protection, landfills projects, etc.
As a kind of pressure-resistant three-dimensional polymer geosynthetic product, Drainage Nets can create a hollow-out structure which allows water and gas to discharge. Moreover, Tinhy’s Drainage Net is designed as a cost-saving and environmental alternative to provide drains for a great number of applications. At the same time, our Composite Geonets can effectively transfer water as well as gas and take up less space than sand, grit or gravel. Drainage Nets are usually used for creating an adaptable space between the two pieces of Geomembranes as a part of leakage detecting system.
Tinhy’s Drainage Nets or Geocomposite Geonets are made of filament needle punched non-woven geotextiles of which thickness is from 5mm to 8mm. Three-dimensional Drainage Nets combine the filtration function of geotextiles and the drainage effect of geonets, which can be applied in many drainage projects of landfills, tailing Ponds, dams, transportations, etc. The filtration function works by using geotextile above or beneath the Drainage Materials so as to stop the clogging of fine-grained fillers in draining channels. Geotextiles are laminated to the surface with fine-grained fillers or to the upper part where the waste can be found in waste areas, and the filter as well as separation features can be obtained with the assistance of geotextiles. What’s more, the featured 3-dimension structure design of our geonets can bear higher compression power and keep the certain thickness.
