Dams & Hydro

At 85 m in height and comprising approximately 1 million m³ of concrete, De Hoop Dam is the largest RCC dam in South Africa.

De Hoop Dam provides the bulk storage for Phase 2A of the Olifants River Water Resources Development Project (ORWRDP), which augments water supply in Limpopo Province. Water is to be supplied primarily to the mining industry in the Steelpoort area.

De Hoop Dam was constructed in high workability RCC and saw the first full implementation of IVRCC; RCC that can be compacted directly against the formwork using poker vibrators, without additional grout.
