Nicolock 8X16 RED 8" x 16" x 2" Heritage Slab Paver Red are fortified with our paver-shield™ technology to ensure a strong, uniform, and consistent result. At two inches thick, they’re strong enough for heavy foot traffic and light-duty vehicle traffic or bikes. You can choose from four different rectangular shapes plus an 18-inch round stone that’s ideal to let grass peek through. Solid color pigments such as Charcoal, Red, and Pewter are blended all through the stone for color that will last for generations. Additional colors by special order are available.
