High Grade Techdrain Pvd

We are a well-reputed firm that manufacture, export and supply an extensive range of High Grade Techdrain PVD in Mumbai, Maharashtra, India.

TechDrains PVD are geo composites with an inner core of polypropylene wrapped in a non-woven geotextile fiber fabric manufactured by Techfab India Industries Ltd.
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.

TechDrain-PVD are used to shorten pore water travel distance, reducing the preloading time. The intent is to accelerate primary settlement. Pore water will flow laterally to the nearest drain, as opposed to vertical flow to an underlying or overlying drainage layer.
