DRAINmasta Vertical Wick Drain

Code: WD140B
U.O.M. - Linear Metre

More Views

DRAINmasta WickDrain prefabricated vertical drains or PVD are suitable for land reclamation projects, construction of highways, railways and airfields, ports and harbour construction, the development of industrial sites and the mitigation of liquefaction.

Details

DRAINmasta Wick Drain is a high-performance, tough and durable vertical drain, designed primarily to accelerate the consolidation of soft soils before construction. It is constructed from high-quality synthetic nonwoven geotextile, and is specifically designed for construction applications, civil engineering, building and industrial applications.

Wick Drain is available by the meter and is 100mm wide with a solid polymer core covered on both sides with a strong and permeable filter fabric. The outer filter fabric is PP sealed through with special ultrasonic welding to produce a quality geo-composite product.

DRAINmasta Wick Drain is a composite producty, with an inner core wrapped in a non-woven geotextile fiber fabric. The inner core is polypropylene and the filter fabrics are of polypropylene or polyester.

Applications:

  • Land reclamation projects
  • Construction of highways, railways and airfields
  • Ports and harbour construction
  • Development of industrial sites
  • Mitigation of liquefaction
  • How Vertical Drains Work:

    Ground improvement with vertical drains has been an accepted practice for improving soft clay deposits for many years. The time required for settlement to occur is considerably reduced as the length of the drainage path through soil is reduced. Vertical drains need to have high permeability and sufficiently high drainage capacity, so that pore water escapes in a horizontal direction towards the nearest drain. The water then flows freely, vertically along the drain, to a drainage blanket placed on the soil surface or to a highly permeable layer above or below the clay layer.

    Consolidation of a compressible soil occurs as pore water is squeezed from the soil matrix. The time for consolidation depends upon the distance the water needs to travel to exit the soil. The installation of prefabricated vertical drains or PVDs such as DRAINmasta WickDrain provides shortened drainage paths for water to exit the soil.
