The installation method for our green friendly permeable pavers is similar to our regular pavers, with a few important differences. In the case of permeable pavers, it is best to use a base comprised of a graded, crushed stone for maximum water infiltration. The voids between the stones provide space to collect and store water for a short period, allowing it time to filter into the earth below. A 1 1⁄2” open-graded stone is preferred. If this I not available in your area, try for a 34” open-graded stone. Most quarries will have a stone close to either size.
