PVD - TechDrain

“TechDrain PVDs are CE certified”

Ground improvement with vertical drains has been an accepted practice for improving soft clay deposits and has been widely used over the 60 years. The time required for the settlement to occur is considerably reduced as the length of the drainage path through soil is reduced. The 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. TechDrains are composite in construction with an inner core wrapped in a non-woven geotextile fiber fabric. The inner core is of polypropylene and the filter fabrics are of polypropylene or polyester.

TechDrain TD3530F

TechDrain TD3530F is a leading product of high-quality synthetic nonwovens for construction applications and three-dimensional and composites for civil engineering, building and industrial applications. TechDrain TD3530F product is manufactured in India with production capacity of 60,000 Linear Meter per day. Laboratory tests and full scale field trials conducted by In-house laboratory and Site Engineers on Site for performance.

Millions of linear meters of TechDrain TD3530F have been installed across India and is one of the leading product of vertical drains in the India. TechDrain TD3530F features for maximum flow through the core with higher flow capacity and has evolved to be a benchmark PVD drain product for ground improvement solutions in India.

Tensile strength of TD3530F is 2500N higher allowing usage on all installation rig types

Suitable for use in all soil types and is easy to handle

Roll length increased to 250 linear meters reduces number of connections on site

30% volume reduction resulting in less storage space used on site

New packaging of 10 rolls to a pack allows faster unloading of container.

Nonwoven Geotextiles Filter cannot tear or become separated from the core when passing over the pulleys at the rig top or during soil consolidation.


Can cut the time required for primary soil consolidation from 20-25 years to just a few months

Most settlement can occur during construction, thus keeping post construction settlements to a minimum


TechDrain is predictable, in both technical and financial terms. PVD technology has proven itself in hundreds of projects in the last thirty years. Over 1 billion linear meters of similar prefabricated vertical drain have been installed worldwide to date.
