PVD Description

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 Application

1)Geotextile can make the water flow easily, and form a drainage channel in the soil, and then make the liquid and gas out of the soil.

2)Make use of its pulling resistance and deformation resistance that can strength the soil to reinforce the stability of the construction structure and improve the soil’s quality.

3) Make the focus proliferate, deliver and decompose efficiently and prevent the soil from destruction from outside factor.

4) Prevent the top and bottom layer’s gravel, soil and concrete from mixer.

5) The mesh cannot be plugged easily – for the strain and moving quality of the network that formed by the antitype fiber.

6) High soaking quality—at the pressure of soil, it also can keep good soaking quality.

7) Corrosion resistant – using the polypropylene and polyester as raw material, it can resist the sour and aid, erosion, boring and oxidation.

8) The construction is easy; the weight is light, convenient for using, and it making construction easy.
