The three-dimensional drainage composite of high density polyethylene geonet and geotextile is a new type of geosynthetics. The structure is a three-dimensional geotextile, and both sides are sticked with needle punched perforated geotextiles. Three dimensional geonet core includes a thick vertical rib, rib and the top and bottom of a tilted. The ground water, which can quickly drain the road, itself has a pore maintenance system that blocks capillary water under high load.


At the same time, drainage composite of high density polyethylene geonet and geotextile can also play the role of isolation and foundation reinforcement. It is a new type of geosynthetics.


The three-dimensional drainage composite of high density polyethylene geonet and geotextile is made of a unique three-dimensional geotextile bonded geotextile. The combination of Geotextiles (filter action) and geo network (drainage and protection) provides a complete "filter - Drainage - protection" effect.


Three dimensional composite drainage network core has unique three-dimensional structure. It can withstand high compression load and maintain considerable thickness during the whole operation process, providing good water conductivity.


Under the climate of the north, the three dimensional drainage composite of high density polyethylene geonet and geotextile can help to reduce the influence of frost heave. If the depth of freezing is very deep, the geo network can be laid in a shallow position in the base, which is blocked as a capillary action. In addition, it is often necessary to replace the grainy subbase, which is not easy to frost, and extend down to the ice depth. The easily frozen backfilled soil can be filled directly to the drainage network until the ground surface line. In this case, the system can be connected to the drain outlet so that the groundwater level is equal to or below this depth. This can potentially limit the development of ice crystals, and there is no limit to traffic load during the spring ice melting in cold regions.
