Banana drains (BD) are particular type of band shaped fibre drains prepared by simulating banana plant stem. They are composite type having two/three parts made mainly with woven, nonwoven and netting materials prepared with jute, coir, caddis and non-retted, non-spurn jute ribbon. They are degradable but their design life time can be extended to 1-10 years by modifications. They have greater consolidation effect than other types of fibre drains on soft clayey soil. Moreover, it is presumed that hydrogen bonds present in lignocellulosic materials play a vital role in determining the permeability of BD when applied in clayey soil.
