3d Composite drainage net

The composite use of three-dimensional composite drainage network and geotextile constituts a complete "filter-drainage-protection" effect and is an ideal drainage geotechnical materials. It is made from high density polyethylene (HDPE) by special extrusion molding technology. It has three special layers, the middle of it is rigid and arranged vertically. It forms a linear drainage channel in the drainage direction. The ribs on both sides are arranged crosswise to increase the overall stability of drainage network.

Product Features

1.Drainage capacity is strong (equivalent to one meter thick gravel drainage);

2. It can withstand high pressure for a long time (it can withstand compression load greater than 3000Kpa).

3.High tensile strength;

4.Reducing the probability of geotextiles embedded into the core, and keeping long-term stable water conductivity.

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

6.Construction is convenient, shorten the cycle and reduce costs.

Product Uses

In railway, highway and other transportation infrastructure construction, the safety and service life of the project is closely related to its own drainage system, so geosynthetics is an important part of the drainage system.
