TerraWick PVD Drain

TerraWick PVD is a geocomposite vertical drain comprising an extruded ribbed both faces polypropylene core and a polypropylene nonwoven geotextile filter sleeve.

PVD drains (Wick Drains) are used to accelerate the consolidation of embankments built on saturated fine grain soils to expedite construction and limit long term settlement. Preloading of the embankment can be designed to induce these settlements in an accelerated time frame and minimise the long term residual settlements to within acceptable limits. PVD drains greatly increase the rate of consolidation, delivering substantial programme savings for the construction time of earth embankments.

No recycled materials are used for the manufacture of the core of TerraWick PVD, only 100% virgin PP is used.
Cores manufactured from recycled materials may pass the required strength test at the first compliance test but a serious decrease in water discharge may result caused by deformation and reduction of the core cross sectional area of the water channels under lateral soil pressure resulting in the ground settlement being delayed

Applications

Land reclamation
Industrial sites
Ports and harbours
Mitigation of liquefaction
Earth embankments
Highways
