Protection of reinforced soil structures using geosynthetic cementitious composite mats

Geosynthetic Cementitious Composite Mats (GCCMs) are geosynthetics that contain cementitious material, which harden on hydration to form a thin, durable, concrete layer. This presentation considers the use of GCCM’s to protect Geosynthetic Reinforced Soil structures. It focusses on the three main applications where GCCMs can be used: a) the provision of a robust facing element to prevent UV degradation, vandalism and animal damage of geosynthetic reinforced wrap faced structures, b) the provision of top of wall drainage to collect surface water and prevent saturation of the reinforced soil block and c) the provision of toe drainage to prevent saturation and erosion of foundation soils. The characteristics and properties of GCCMs relevant for each application are reviewed and compared with traditional concrete solutions to determine when they can be used to protect Reinforced Soil structures.
