Verti-Drain® is a prefabricated pocket-style vertical drain (PVD) for the improvement of soft ground made from a mechanically strong PP core and a nonwoven filter jacket specialized as PVD filter material.
Verti-Drain® significantly reduces the time needed for construction by discharging pore water in the ground and therefore speeding up soil consolidation. Verti-Drain® allows for the safe construction of seaports, airports, roads, embankments, railways, water supply facilities, tunnels and many other mega-scaled structures.
Since Verti-Drain® is produced with filter materials having AOS in the range of 50㎛~90㎛, which is suited 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 polypropylene, which does not allow contaminants or hydrolysis.
Verti-Drain® has achieved CE certificate and the product reliability certificate, “R-mark”, related to a long-term performance and durability from Korean Government. It was first time these certificates for PVD products have been achieved in Korea.
