Elastocoast is a special elastomeric polyurethane system made by Elastogran. It binds broken rocks or stones together to form a stable material which is not only solid but also elastic so that it is able to be an ideal material for hydraulic applications. As a new developed material for revetment, the performance of Elastocoast in the application of revetments is still unknown. This research is carried out to study the feasibility of the Elasatocoast's applications as revetments. Due to the similarities between Elastocoast and open stone asphalt, most of the experiments are done according to the concerning problems of the open stone asphalt revetments. Five properties were tested: porosity, permeability between the material and geotextile, wave run-up, stability on slope and resistance to erosion. It turned out that compared to open stone asphalt Elastocoast is a strong and permeable material and it is relatively easy to construct and maintain. It is expected to be a suitable material as revetment.
