A GCCM is a factory assembled geosynthetic composite consisting of a cementitious layer contained within one or multiple layers of geosynthetic materials. The cementitious portion of the GCCM becomes hardened when properly hydrated. GCCM is a flexible, concrete-filled geosynthetic that hardens on hydration to form a thin, durable, waterproof and low-carbon concrete layer. Common applications are erosion control, channel lining, bund lining, slope erosion protection, culvert lining, spillways and weed suppression.
