Prefabricated Vertical Drain (PVD) wick drain for soft soil drainage and ground settlement projects
What is Wick Drain?
Prefabricated Vertical Drain (PVD) is a composite product of plastic strip with outer nonwoven geotextile layer.
PVD gets excellent physical, mechanical & hydraulic performance, which make it an effective solution of
Soft Ground Improvement to accelerate construction and reduce both time and magnitude of postconstruction settlement.
Structure of Wick Drain?
Prefabricated Vertical Drain (PVD) PP material Wick Drainage Plate
for soft soil treatment
1.The core boards are made of mixture from PP and PE, so it
combines the rigidity of PP and the flexible and
weather-resistant capabilities of PE.
2.Filtration membrane is made of non-woven fabrics, permeability
and water logging ability enjoying good.
3.Filtration membrane are firm together when wrapping the core
board by ultrasound.
