Abstract: The main objective of this study is to provide readers an overview to the potential use of coir fibres in various forms and methods in civil engineering applications. The paper is based on the comprehensive review on the applications of coir fibres in different media and forms such as used for insulation, as reinforcement member in concrete, to provide reinforcement to soil mass in embankments and foundations, in casting light weight cement boards for soundproof walls, cement blocks, etc. As we all know coir fibres are available in abundance in tropical regions as well as in cities of religious importance, we can lay emphasis on high usage of coir fibre in civil engineering. Further potential uses of such a valuable waste can be thought upon.
