Hydromedia is a new, fast-draining concrete pavement solution engineered to rapidly direct stormwater, a major source of pollution, from streets, parking surfaces, driveways and sidewalks. The aggregate matrix is designed to minimize compaction and provide permeability in the final hardened product. Hydromedia reportedly minimizes long-term maintenance costs and is intended to be a sustainable solution that combines the durability of concrete with triple bottom line values as defined by the ICLEI. www.lafarge.com
