Abstract: This work proposes improvements on the assembly process of a slope protection system using scrap tyres to reduce severe erosion that occurs in non-vegetated slopes. Tests results during six rain events, with maximal intensity of 26 mm/hr and accumulated rainfall of 94.5 mm, indicate that the installation cost of the system was $1.10USD/tyre and reduced the erosion by 83% with respect to an unprotected area. Further improvement undertaken by students from the graduate course Product Design and Analysis indicates that by replacing the rope on the original system with straps, the installation time is reduced by 75% and the material costs by 18%.
