This paper presents a novel solution by taking into account of safety and sustainability to cope with a damaged slope. The rehabilitation consists of a piled supported reinforced concrete protection wall and a reinforced soil slope (RSS) with geosynthetics. Such approach is not common; however, the experience described herein has shown that the reported composite retaining structure meets all the site criteria. RSS demonstrated competent safety and significant carbon footprint reduction compared to those of traditional reinforced concrete structures. RSS also successfully made a vegetated terrain that has pre-sented a natural appearance and provided an aesthetic and eco-friendly environment for the site. Based on field observations, the slope is stable and safe to date. It is a valuable and sustainable solution particularly for those sites that have a major concern with basal instability due to scouring effect.
