Permeable 4.5" x 9"
Produced with a 1/16” bevel and hidden spacers, Hanover’s Permeable 4 1/2” x 9” meets standards set forth by the Americans with Disabilities Act (ADA). Minimal openings providing a comfortable walking surface while allowing for water percolation. The Permeable 4 1/2” x 9” x 3” will provide the project with 5.8% open space allowing water to be infiltrated at a rate of 7” to 8” per hour based on proper installation methods. The Permeable 4 1/2” x 9” can accommodate wheel chair traffic, pedestrian traffic and heavy low speed vehicular loads. Sized at 4 5/8” x 9 1/4”, the Permeable 4 1/2” x 9” is a true rectangle, providing the correct size ratio to create interlock stability.
