SBC SinkCrete allows contractors to perfect sink fabrication. Sinks can be installed as an overmount, undermount, or high-end vessel. Monolithic sinks in counters can be saved for special orders, increasing efficiency. Higher densities and 100% stain-free, chemical-resistant mixes allow quick and easy cleaning. Material formulation yield higher than average strength and overall weights are significantly lighter than standard GFRC and other common mix designs. Something Better Co. LLC. 800-324-1719.
