Federally Funded research shows that GeoSynthetically Confined Soil (GCS®) structures have bearing capacities up to 20 times those of traditional Mechanically Stabilized Earth (MSE) walls. State of the art GCS® technology translates into better retaining walls, bridge abutments, box culverts, foundations, rockfall barriers, avalanche and debris flow deflectors, and more.
Facing options include natural vegetation, wire mesh, natural stone, concrete block, or sculpted shotcrete.
The key to GCS® performance is close (8 inch/200mm) reinforcement spacing with compacted granular backfill. The reinforcement induces confining effects in the soil up to four inches (100mm) from each sheet. That confining effect explains why GCS® structures built with even the lightest fabrics can withstand loads up to 22.5 tons per square foot (2.2 MPa) while MSE structures can fail under self weight.
