Description
Prefabricated Vertical Drains, also called Wick Drains.
Prefabricated Vertical Drain(PVD) is a composite product of plastic strip with outer nonwoven geotextile layer. It is widely used for soft ground improvement due to its excellent physical, mechanical and hydraulic properties. PVD is an effective solution for soft ground treatment in minimizing the settlement issue after construction.

Specification:

Thickness: 3.5mm, 4.0mm, 4.5mm.

Width: 100±2mm

Roll Length: 200mm

Applications 
PVD is applied to reduce construction time and speed up the consolidation of soft ground for the following work:

1.  Improvement of dredged clay fill
2.  Road, railway and airport construction
3.  Development of building and industrial complex site
4.  Development of seaport area
5.  Bank revetment
6. Construction of gas and oil storage facilities.
