Drainage is an evitable part for structures such as earth retaining structure, reinforced soil structure, abutments etc. Locking of water inside the structure shall impose extra water pressure and earth pressure that results in reduction in shear strength of soil. This shall reduce the stability of structure and can even lead to catastrophic failure. To prevent this, 600 mm thick filter media (cobbles or boulders in railway project/graded aggregate in highway projects) layer is provided behind retaining wall towards the backfill soil face and larger size towards the wall face. This conventional method has a lot of hindrances like: Clogging of filter layer by fine soil particles, difficulty in quality construction (as there is a need to provide proper gradation of aggregate depending upon the fill material and it is difficult to place the handpicked boulders one above the other in case of railways) etc. Considering these aspects, the paper present use of an advanced geo-synthetic material, Geo-composite drain as an alternative to the conventional filter media.
