Irrigation and drainage are extremely important in landscape maintenance, agricultural crop care, and revegetation in arid areas. A good drainage system is always coupled with a irrigation system, for the removal of surface or underground water by natural or artificial means. It includes a coating consisting of a robust concrete layer to protect the river bed and its banks from water pressure. The benefit of the concrete layer is to save water to extend irrigation, minimize leakages, improve work, reduce maintenance costs and prevent the growth of wild plants. The efficiency of Carmix truck mixers is therefore essential to ensure the highest quality concrete, wherever it is needed.
