Sand washing the future of Africa's construction industry

Depleting water and sand resources on the African continent, combined with stricter aggregate specifications and multiplying bans of river sand mining in some countries such as Kenya present a fresh opportunity to explore water-saving sand and aggregates washing as a profitable alternative to river sand mining. 


CDE Global specialises in manufactured sands and its presence in Africa has grown steadily in the past years. With experts from an engineering background based in South Africa and travelling across Sub-Saharan countries, CDE Global is able to understand, and crucially respond, to changing industrial, economic and geographic environments as well as clients’ needs. 

“Africa is mineral-rich and a wide range of rock types can be used for crushing, including dolerite, granite and dolomite amongst others. "However, crushing alone more than often cannot produce a manufactured or ‘engineered’ sand of sufficient quality. Sand and aggregates washing using a reliable, water-recycling combined installation, such as the CDE X70, optimises return on investment and quality outputs by maintaining consistency and increases productivity, delivering ready to use concrete and/or plastering sand at the correct moisture level, within the client’s time and quantity requirements." “With a water recycling rate of 90%, the CDE AquaCycle technology adds extra return-on-investment value to any installation that requires high levels of water recovery".
