Geosynthetically Confined Soil (GCS) Services

Geosynthetically Confined Soil (GCS™) Services

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.
