TechDrains PVD are geo composites with an inner core of polypropylene wrapped in a non-woven geotextile fiber fabric. The Prefabricated Vertical Drains are required to have high permeability and sufficiently high drainage capacity so that pore water escapes in 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. We manufacture two types of PVD – Corrugated PVD, Fishbone PVD
