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.
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.

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

Wick drains are installed with specialized equipment, called stitchers. The stitchers, which are mounted on either backhoes or excavator consist of a vertical mast housing a special installation mandrel. The mandrel, containing the wick drain, is hydraulically pushed or vibrated into the ground to the desired treatment depth, typically to the bottom of the soft-soil stratum. As the mandrel is withdrawn back into the mast, the undamaged wick drain is left in place within the soil mass.
Wick drain projects have included dams, large storage areas,
highway embankments, sedimentation ponds, tanks, bridge abutments,
buildings, and airport runways.
The most common application of wick drains is for accelerating the
settlement rate of compressible soils. At some sites, the primary
purpose of wick drains is to increase the shear strength of
underlying soft soils. As soil consolidates, the shear strength
increases due to a reduction in the water content. This application
is particularly important when high area fills have to be placed
over soft soils with low shear strength. Potential instability
problems can be overcome by loading the site in stages and allowing
the soft soils to gain in strength under each stage before
placement of the next stage of fill.
