Drainage Geonet with high density polyethylene (HDPE) as raw materials, through special process, the two root rib in a certain distance and Angle arrangement, staggered at the intersection of double rib form drainage channel. Has high tensile strength and compressive strength, rib between a drainage channel in the higher load is out of shape not easily, it can prevent geotextileembedded geotextile net core, ensure drainage unblocked.

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

2. High tensile strength.

3. To reduce the probability of geotextile embedded core, to maintain long-term stability of the drainage.

4. Long-term high-pressure load (can withstand about 3000Ka compression load).

5. Corrosion-resistant, acid and alkali, long service life.

6. Construction convenience, shorten the construction period, reduce costs.

1. Landfill drainage;

2. Highway roadbed and pavement drainage;

3. Railway subgrade drainage;

4. Tunnel drainage;

5. Underground structure drainage;

6. Retaining wall back drainage;

7. Garden and playground drainage.
