Product Description:
Three dimensional composite drainage geonet is a new type of geotechnical drainage material. It is made of high density polyethylene (HDPE) by special extrusion process, with three layers of special structure. In the transportation infrastructure such as railway and highway, the safety and service life of the project are closely related to its own drainage system. Geosynthetics are important parts of drainage system. The middle bar is rigid and arranged longitudinally to form drainage channel. The upper and lower cross bars form support to prevent geotextile from embedding into drainage channel, which can maintain high drainage performance even under very high load.
Double-sided adhesive geotextile compound using, with "filter - drainage - air - protection" comprehensive performance. It’s the most ideal material of drainage now.They can replace the traditional sand and gravel layer, Mainly used in drainage of landfills, roadbed and tunnel lining.

Application:
Basements:
Basement flooding is caused when water flows behind walls and under floors. The resulting pressure forces water through joints and cracks into the building’s structure where it causes damage. Cordrain releases this pressure by draining excess water from these areas.
Bridge Abutments:
Cordrain drainage systems are ideal for vertical applications such as bridge abutments, where space is limited but high groundwater levels make water drainage necessary. Cordrain has a thick flexible structure which prevents damage from backfill material.
Retaining Walls:
Cordrain is a reliable alternative to granular drainage systems traditionally used in retaining walls. The compact Cordrain system has proven more cost effective thanks to its low transportation and installation costs..
Advantage:
1. Good drainage function(equal to one meter thickness gravel‘s drainage )
2. High tensile strength
3. Anti-Corrosion,anti-aki,long lifespan
4. Load the high pressure in long term
