The Quattro series concrete rooftop and on-grade pavers use a four-color blending technology to combine the look of porcelain with concrete pavers. The pavers provide a reported unprecedented compressive strength and weight, rated at a minimum of 9,500 PSI and 22 lb./sq. ft. with exceptional load capacity. Four distinct finishes include blasted, unblasted, slate, and wood grain. Products provide wind-uplift resistance and are backed by hurricane condition testing.
