With its unique, patented interlocking spacer lugs Eco-Priora permeable pavers provide secure structural performance. It works very well under heavy vehicular traffic, especially when compared to other “rectangular” permeable pavers. When designed in a permeable pavement system, LEED® “heat island” and “runoff” credits may be available. Eco-Priora’s flat surface is well suited for pedestrian and ADA (Americans with Disabilities Act) accessible pavements.
