Breton™ permeable pavers provide the appearance of an old granite paver that has been in the ground for centuries. This three-piece system is crafted with a natural stonecleft finish. Enlarged lugs on the sidewalls of the units create quarter-inch joints which, when filled with a properly-sized aggregate, drain water to the permeable base. This infiltration filters stormwater, reduces peak flow rates, and recharges groundwater sources to create a sustainable pavement option.
