This product is available in the following size: 3 1/8 x 7 1/2 x 15 (in). Zen pavers are an eco-friendly and aesthetic solution for parking spaces. With built-in 40 mm spacers on one side only, Zen pavers give you the choice of spacing, depending on the installation: back-to-back, face-to-back or face-to-face. These low carbon footprint pavers, filled with clean aggregates or vegetation, significantly reduce erosion, ensure natural stormwater infiltration and provide thermal and water regulation. With the same format as Melville Small Rectangle pavers, Zen pavers are a permeable alternative to the popular Melville small rectangle pavers.
