As the development of the Saldanha Bay Industrial Development Zone (SBIDZ) progressed over the last few years, the need for effective storm-water control arose, especially with new tenants taking up residence this year.
Following the Integrated Development Plan (IDP) for sustainable infrastructure development, the main contractor, Power Group, stipulated a permeable, environmentally-friendly solution. “Having considered all options, we settled with the Terracrete block manufactured by Van Dyk Precast in Vredenburg, confident to have found the best solution for the least environmental impact on the area,” says Robbie Dreyer, senior site agent for Power Group.
The Terracrete permeable paving blocks encourage water infiltration and prevent rainwater runoff, to replenish dwindling groundwater reserves. The grass paver is ideal for areas prone to erosion, and the versatile blocks can be used for domestic, industrial and agricultural applications such as driveways, parking areas, vehicle tracks, hardstands for trucks and machinery, attenuation ponds, embankment stabilisation and more.
Installed by Keystar Trading and Cleophas Construction early this year, the entire SBIDZ has been supplied with a network of permeable storm-water channels that will effectively collect and redirect excess rainwater to the appropriate culverts, with some of it passing through the large holes in the Terracrete blocks into the sub-terrain water reservoir. This will encourage low shrubs to take root and reduce wind and water erosion in the area.
Not only are permeable pavers a good solution to manage storm-water runoff, but according to Dr Sönke Borgwardt, landscape architect and consulting engineer, and leading expert on the subject in Germany: “The use of permeable paving is an important contribution to sustainable and environmentally useful management of drainage systems.”
