Complex shapes, light weight, and finishes that match.
Glass fiber reinforced concrete (GFRC) and glass fiber reinforced polymer (GFRP) deliver complex architectural shapes and finishes without the weight of precast.
Caston coordinates the engineering, shop drawings, and custom finish work so panels match the architecture, including exposed aggregate finishes matched to existing buildings.
