Peer-reviewed research proves 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 & 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 (200mm) reinforcement spacing with compacted granular backfill. The reinforcement induces confining effects in the soil up to 100mm from each sheet. That confining effect explains why GCS® structures built with even the lightest fabrics can withstand loads up to 2.2 MPa while MSE structures can fail under self-weight.
