Prefabricated Vertical Drain (PVD)

Prefabricated Vertical Drain (PVD)

     Geoguard PVD is made of polyethylene and polypropylene as core board and wrapped  by non-woven fabric as filter jacket. Core board is to play a supportive role and drain the leaking water and air out of ground.

     PVD is inserted into soft soil foundation by PVD installer equipment. The pore water in soft soil will be drained out through prefabricated vertical drain to the soil's surface under the action of upper pre-pressure loading, and drain outward to accelerate the soft ground consolidation.
