Composite drainage network is currently the most ideal drainage material

      The composite drainage net consists of a three-dimensional plastic mesh double-sided bonded water-permeable geotextile, which can replace the traditional sand and gravel layer, and is mainly used for drainage of landfills, roadbeds and tunnel inner walls. The technical parameters and product specifications of the composite geotechnical drainage network are inseparable from the safety and service life of the railway infrastructure, such as railways and highways. The geosynthetics are an important part of the drainage system.

    The three-dimensional composite drainage network is a new type of geosynthetic material. The composition is a three-dimensional geonet core with a needle-punched perforated nonwoven geotextile on both sides. The three-dimensional geonet core includes a thick vertical rib and an oblique rib at the top and bottom. It is able to quickly discharge groundwater from the road and has a pore maintenance system that blocks capillary water under high loads. At the same time, it can also provide isolation and foundation reinforcement. A new type of geosynthetic material.

    The three-dimensional composite drainage net is made of a unique three-dimensional geonet double-sided bonded geotextile. The combination of geotextile (reverse filtration) and geonet (drainage and protection) provides a complete "reverse filtration - drainage - ventilation - maintenance" induction function, which is currently the most ideal drainage material.

Composite drainage net features:

1. Strong drainage (equivalent to one meter thick gravel drainage).

2. High tensile strength.

3. Reduce the probability of geotextiles embedded in the core, and adhere to long-term stable drainage.

4. Accept high pressure load for a long time (can accept a compression load of about 3000 Ka).

5. Corrosion resistance, acid and alkali resistance, long service life.

6. Convenient construction, shortened construction period and reduced costs. The unique three-dimensional structure of the three-dimensional composite drainage net core can withstand high compressive loads throughout the use process and maintain a considerable thickness, providing a good water conductivity.
