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. The GCS™ services provided by GeoStabilization International® cover a broad range of solutions including better retaining walls, bridge abutments, box culverts, foundations, rockfall barriers, avalanche & debris flow deflectors, road repairs, 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.
