Uni Eco-Stone™ makes efficient use of land that might not otherwise be developed because of storm water retention and limitations on the impervious areas allowed on a site. This paver gives the designer a tool to minimize the environment's impact on land development. Made with the same strength, durability and aesthetics as solid concrete pavers, Uni Eci-Stone™ is a natural way to handle storm water runoff, conserve rainwater, recharge groundwater storage, improve water quality and mitigate pollution on surrounding surface waters.
