Concrete countertops with undermount sinks. Rich texture and color variations. Smooth molded edges with up to 16" unsupported overhangs. Our countertops are 3/4" GFRC (Glass Fiber Reinforced Concrete) for strength. Our integral edge reveals are most commonly 2" thick to give it a substantial stone look. The edge reveal options are limitless. Enhance the natural stone appearance with our custom veining technique or texture then bring those features out with a complementary color.
