Mbizana, South Africa
Ludeke Dam, pump station and rising main form of the raw water components of the Mbizana Bulk Water Supply Scheme initiated by Umgeni Water. Stretching 240 m in length and standing almost 40m high, the dam will hold in excess of 14.5 million cubic meters, providing a much needed supply of water to surrounding communities consisting of 266,000 people.
Sika put together a proposal for Rumdel Cape providing solutions on which products would best suit the mix design that they were looking for. Rumdel Cape then approved Sika’s proposal to supply the concrete admixtures. The concrete had to be designed for various applications:
- Base of intake towers
- Concrete Spillway
For the first phase of this project, Sika supplied SikaPlast-V210 as the concrete admixture used to construct firstly the base of the intake towers of the dam, then the entire structure of the intake towers, as well as all the spillways. The proposed concrete mix designs fulfilled all the project requirements.
Additionally, Sika supplied a number of other high performance products, thereby assuring Umgeni Water of the highest quality of this crucial project upon completion.
