Reinforced Soil (RS) Walls using geostrips are modern, engineered retaining structures that combine compacted granular backfill with high-strength polymeric reinforcement to form a stable, composite earth mass. The core reinforcing element is the geostrip, a planar, flexible tensile member installed in layers to resist lateral earth pressures and enhance stability. TenGeo Geostrips, manufactured using high-tenacity polyester filament tendons encased in a durable LLDPE sheath, offer exceptional tensile capacity, excellent durability, and long-term performance—making them ideal for demanding infrastructure applications.
A typical RS wall comprises a reinforced soil zone, a facing system (such as precast concrete panels) and selected granular backfill. The geostrips are laid horizontally between compacted soil layers and extend sufficiently beyond the potential failure plane to develop pullout resistance. Their engineered surface texture and low-creep polyester core ensure reliable interaction with the backfill, while the protective sheath safeguards against installation damage, chemical exposure, and environmental effects.
Design Standards
The design of geostrip-reinforced soil walls is based on well-established principles that address internal stability (tensile rupture and pullout), external stability (sliding, overturning, bearing), and global stability. Standards such as BS 8006, FHWA, BIS, IRC guidelines provide the design framework.
