Techfab India Industries Ltd.
TechDrains are prefabricated subsurface drainage products that directly replace the granular drainage layer completely or partially. These are used for reinforced soil wall retaining structures. TechDrain Drainage Composites provide mediums for guiding groundwater and seepage water to drainage pipes/weep holes, and they reduce the pore pressures on the wall. It prevents the intermixing of the backfill soil with filter media, thus avoiding the clogging of the filter media. The main objective of TechDrain material is to combine the best features of different materials in such a way that specific problems related to drainage, filtration and separation are solved in optimal performance and minimum cost. TechDrains are convenient to place.
