Why is TECHDRAIN the ideal drainage geocomposite for landfills?
1. High drainage capacity under any slope or load.
2. Great resistance to crushing (stands installation processes)
3. Excellent behaviour in terms of creep (or fatigue), guaranteeing long-term drainage
4. Great durability, as it is made up of PP and HDPE, chemically stable elements that not rot, are not sensitive to salt water and are resistant to oxidation and microorganisms.
5. HDPE is the polymer offering the greatest durability when confronted with leachates.
6. It is the most widely used drainage geocomposite in landfills in Spain and Portugal.
7. It has the CE mark, the requirements of the UNE 104425 standard. Synthetic materials. Implemention. Waste landfill sealing systems with high-densiy polyethylene (HDPE) sheets.
8. Great resistance to traction and elongation, suitable for use on slopes.
9. The geotextiles used have small openings ideal for preventing them being filled in (70 µ < 0 90 < 130 µm)
10. The geotextiles used have excellent friction properties with HDPE geomembranes and bentonite sheets (GCL)
