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.

Rocla, specialist in precast concrete infrastructural products and solutions, showcased two of its new products at the annual IMESA Conference and Exhibition in October last year. The Rocla stand featured the new lightweight precast Wingwall units and the locally manufactured Alfabloc systems. Rocla is the first concrete manufacturer in South Africa to offer a complete range of precast Wingwall units to the market. These units have applications in culvert and storm water installations to ensure optimum hydraulic flow at both the inlets and outlets of these structures.

A civil engineering project using Technicrete’s Armorflex concrete erosion-protection blocks to prevent storm-water flooding of an open-cast platinum mine in the Pilanesberg, near Rustenburg in North West Province, is nearing completion. According to the engineers, the Armorflex solution is also saving millions of rand in construction costs over original estimates.
