Technicrete’ s Armorflex 180 erosion control system was selected for stormwater channel management in a new housing development, The Orchards Ext 116 in Pretoria North. The Armorflex 180 system is a uniquely engineered alternative for a wide variety of erosion control and drainage projects which offers flexibility, adaptability to ground contours, settling of the concrete mat without breaking or spalling of individual blocks and with limited ground preparation work required. Technicrete supplied a total of 7 594 m² of Armorflex for this project.
