Competing against the best, Rocla and Technicrete were honoured with Engineering Excellence Awards in the Infrastructure and Paving categories at the Concrete Manufacturers Association (CMA) 2022 Digital Awards for Excellence.

“The CMA’s recognition adds value to the entire Rocla and Technicrete teams’ efforts to deliver a superior solution,” says Malebusa Sebatane, group manager: Marketing and Communications for the ISG Group, which owns the Rocla and Technicrete brands. Rocla, winner of the Infrastructure category, supplied over 19 km of HDPE lined precast piping to Safcrete Construction for the Polokwane Wastewater Treatment Project.

The latter was commissioned by Polokwane Municipality to upgrade an outdated sewerage system servicing the Seshego area. The precast concrete pipes supplied measured 1 980 mm x 1 000 mm and 2 116 mm x 900 mm. The placement of each pipe also required the insertion of a rubber ring and the welding of a ‘capping strip’ on the inside of each individual joint to ensure a proper seal.

Amorflex

Announced as the winner of the Paving category, Technicrete’s internationally licensed Armorflex Erosion Control System 140 was selected for upgrades to major stormwater systems in Mamelodi Ext 4 and 5 north-east of Pretoria. Tefla, who undertook the project, said Armorflex’s easy installation enabled the company to outsource 30% of the work to the local community, facilitating a skills transfer element in the project. Based on a trapezoidal channel analysis of water volumes and velocity, Armorflex 140 was selected as the best system to install for the gradual channel to be constructed.
