The application of geotextiles in stabilising weak ground and improving performance of irrigation features like canal lining is well known in the field of civil engineering. The geotextile is also used to serve as wick drains. In recent years some attempts were made to use geotextiles as a sacrificial liner for bored cast in sit piles. Such liners are expected to protect concrete from aggressive environment, reduce negative skin friction and ensure integrity of shaft by eliminating necking of piles.
Since the geotextile liners are quite cheap as compared to conventional steel liners the temptation to use it is very high. The authors have been associated with the construction of piles with geofabric as liners. The experience was not too pleasant. The paper discusses the field problems and performance of such liners and mechanics of behaviour.
