Product details
Composite Geonet is a new type of drainage geotechnical material. It is made of high-density polyethylene (HDPE) as raw material and processed through a special extrusion molding process. It has a three-layer special structure. The middle ribs are highly rigid and are arranged longitudinally to form a drainage channel. The ribs arranged crosswise up and down form a support to prevent the geotextile from being embedded in the drainage channel, and can maintain high drainage performance even under high loads. The double-sided bonded permeable geotextile is used in combination and has the comprehensive performance of "reverse filtration-drainage-breathability-protection" and is currently the most ideal drainage material.

Main Feature
1. Strong drainage (equivalent to one meter thick gravel drainage).
2. High tensile strength.
3.Reduce the probability of geotextile inserting into mesh core, and maintain long-term water conductivity.
5. Corrosion resistance, acid and alkali, long service life.
6. Convenient construction, shorten the construction period and reduce costs.
