With ever-increasing urbanisation and the resultant sprawl of rooftops and hard-surfaced landscapes, the effective management of storm water drainage has become increasingly difficult. The risk of flash floods escalates and the impact of rapid runoff on natural watercourses can cause serious environmental damage. Lafarge Readymix has launched Hydromedia™, a new, fast-draining concrete pavement solution to address this problem in South Africa. Hydromedia provides for rapid storm water removal from streets, parking areas, driveways, walkways and other hard surfaced areas. It offers a drainage medium that enables rainwater to return to and replenish groundwater reserves locally and it can reduce the costs and long-term maintenance requirements of storm water management systems – for public authorities and private property owners.
