Geosynthetic reinforcement products may be geogrids or geotextiles, although most SRW construction has used geogrids. Geosynthetic reinforcement materials are high tensile strength polymeric sheet materials. Reinforced soil SRWs utilize geosynthetic reinforcement to enlarge the effective width and weight of the gravity mass. The maximum height can be increased by implementing a conventional crib wall approach, using multiple depths of units to increase the weight and width of the wall. The maximum wall height that can be constructed using a single depth unit is directly proportional to its weight, width, unit-to-unit shear strength and batter for any given soil and site geometry conditions. The majority of available SRW units are dry-cast machine-produced concrete.Ĭonventional SRWs are classified as either single depth or multiple depth. Both types of SRWs use dry-stacked segmental units that are typically constructed in a running bond configuration. Segmental retaining walls (SRWs) are gravity retaining walls which can be classified as either: conventional (structures that resist external destabilizing forces due to retained soils solely through the self-weight and batter of the SRW units) or geosynthetic reinforced soil SRWs (composite systems consisting of SRW units in combination with a mass of reinforced soil stabilized by horizontal layers of geosynthetic reinforcement materials).
