Earth Retention

Geotextiles are essential in earth retention systems, particularly those using modular block walls or vegetated slopes. In these applications, non-woven geotextiles are typically placed behind the retaining structure to provide filtration and drainage, preventing soil migration while allowing water to pass through. This helps reduce hydrostatic pressure and maintain long-term wall stability. A successful retention system includes several integrated components: the retaining structure itself (such as concrete blocks or vegetated lifts), reinforcement layers like uniaxial geogrids for tensile strength, drainage aggregate to manage water flow, and geotextiles to separate soil and aggregate while supporting filtration. In vegetated systems, additional elements like erosion control blankets or turf reinforcement mats may be used to promote vegetation and surface stability. Together, these components work to ensure structural integrity, manage water, and support aesthetic or environmental goals in both residential and commercial site development.
