Setting the standard in durability and surface defense, Sentinel Sealed Technology™ combines modern engineering with time-tested European innovation. This advanced manufacturing process ensures consistent quality and durability from the start, providing maximum stain resistance, surface protection, and long-lasting color. Unlike field-applied sealers or single-layer primers, County Materials has crafted a hybrid paver manufacturing system that bonds two protective layers—a factory-applied penetrating primer and sealer—to the pavers’ surface. The result is an ultra-smooth finish and refined texture—an ideal solution for pool decks, patios, and other barefoot-friendly spaces. Sentinel integrates concrete’s inherent durability with an engineered protective seal designed to withstand life’s greatest moments and inevitable messes.
