Hanover's Permeable 4 1/2” x 9” Scored is perfect for large driveways, parking lots, roads and industrial applications. Because it is designed to be installed mechanically, installation time and costs are reduced. Pavers are laid layer by layer through the use of a machine increasing speed and efficiency. Each layer is composed of four different units to provide maximum interlock with a random appearance. Produced with a 1/16” bevel and hidden spacers, the Permeable 4 1/2” x 9” Scored meets standards set forth by the Americans with Disabilities Act (ADA). Hanover's Permeable 4 1/2” x 9” with score is made to order in standard and custom colors when quantities permit.
