In order to utilise coir fibre, which is abundantly available in coastal India as an inexpensive material, in foundation beds, an investigation is taken up. Drained triaxial tests were performed on specimens of sand reinforced with coir fibres (25 mm and 50 mm long) upto 1 % . The results are very encouraging in that the behaviour is similar to that observed in synthetic fibres and meshes. Considering that coir has a longer life compared to other natural fibres which degrade much faster, it is possible to use this method in rural housing for foundations.
