A study was conducted into the use of a natural, biodegradable geotextile for the containment and control of soil erosion. The viability of using the natural fibre from the sisal plant (Agave sisalana) for the manufacture of such a geotextile was assessed and the performance of this material was compared to more commonly used fibres like coir and jute. This report provides a brief summary of the various laboratory and field tests which were used to evaluate the different materials and some significant test results. The report shows that sisal fibre compares very favourably with other natural fibres. The sisal fibre geotextile provides protection against soil erosion for a period of up to two years while at the same time creates a suitable micro-climate for the germination and growth of new vegetation.
