Alpine Ridge paving stones come in a variety of attractive color blends. The paving stones are made with Nicolock’s patented paver-shield™ technology, which ensures that each paving stone has even color throughout. This is achieved by using a special blend of ultra-find sand, Portland cement and extra pigment, all precisely measured and manufactured in Nicolock’s state-of-the-art manufacturing facility. Paver-Shield™ paving stones are fade resistant for your outdoor living spaces. Alpine pavers are sold by the pallet, and each pallet covers approximately 127 square feet.
