Aquadam's Muleby System Tank originated in Muleby in Belgium with the MST1. The Muleby Tank system is a prefabricated, modular concrete tank. This tank uses the old technology of pre-stressing and post-tensioning. For the first time in South Africa, pre-stress and post-tension is used in unison, making use of concrete best asset as it functions best under pressure. High quality pre-cast, pre-stressed elements are placed on a site-specific, cast in situ concrete floor. Poly ethylene-coated post-tension cables are fed through the elements and post-tensioned in the horizontal direction to pressures in excess of 135 KN. These tensions are calculated for the tanks' specific application. These cables are placed internally and the stressing point closed to protect against corrosion.
