Floradrain

Introduction:
Clay soil has a low permeability and hence pore water trapped in the soil cannot come out in a short time period. Floradrain (FFD-8) prefabricated drain can be installed vertically to depths as great as 40 m. Water, under pressure in excess of hydrostatic pressure, flows through the Jute filter sheath and into the core coir channels where it is led vertically out of the soil. This may be either up or down to intersecting natural layers or to the surface where a sand drainage blanket or Jute-coir prefabricated strip drains are provided. The water in the soil has to travel the distance to the nearest drain to reach a free drainage path. The drains are usually placed in a triangular configuration of 1 to 10 metres - depending on the desired consolidation time. As a result of this method of accelerating the consolidation process, uneven post-construction settlements can be virtually eliminated.

Application:
Accelerated settlement and consolidation of construction over soft soil like Road Rail embankments, underwater constructions, Foundations for tank farms and material storage areas, Land Reclamation etc.
