All Nicolock pavers have color throughout the full thickness of the paver. Pavers made with Nicolock’s patented Paver-Shield™ manufacturing technology have an ultra dense surface and richer, more vibrant color that will not fade. Our technology starts with more color, cement, and a very fine aggregate on the wear surface. Although “smooth as silk” in appearance, pavers with Paver Shield have great slip resistance when used on walkways, patios, driveways, and pool decks. Nicolock’s exclusive Paver-Shield™ provides superior protection.
