Geocomposite Prefabricated Vertical Drain (PVD) Filter bonded with Core wick drain for soft ground settlement projects

 

What is Wick Drain?

 

Ground Pvd Prefabricated Vertical Drain Geocomposite Drainage 0
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.
