Verti-Drain®
Prefabricated Vertical Drain (wick drain) for Soft Ground Improvement
Overview
Verti-Drain® is a pocket-style prefabricated vertical drain (PVD) for the improvement of soft ground made from a mechanically strong PP core and a nonwoven filter jacket specialized for PVD application. The product quality of Verti-Drain® is assured by many certificates including ISO9001, CE, Q-mark, R-mark, Eco-Label, etc.
Since Verti-Drain® is produced with filter materials having AOS suitable for the improvement of soft soil, filter clogging can be prevented over a long term. Verti-Drain® is resistant to friction and scratching caused during its installation and also has a physically durable structure with a high strength. Verti-Drain® has a high resistance to bacteria and chemicals. Verti-Drain® is materially and ecologically stable since it is made of polymers which don’t cause contaminants.
