Transforming for change
The mark of any world class organization is an ability to change within the needs of a changing environment. Broadening its service offering, the now Eskom Rotek Industries entered the construction, bulk material handling and logistics arenas in the 1990’s. These services are still in existence today and compliment the maintenance services already provided with three alone standing business units.

Bulk Material Services specialises in bulk material handling for coal, ash, limestone and gypsum, water services, project management and related engineering solutions. In addition, it also offers plant maintenance, water treatment solutions, coal transportation logistics and the selling of coal combustible products such as ash, gypsum and salts.

Construction Services specialises mixed civil construction projects focusing on earthworks, concrete works and drainage, fencing, water management solutions, as well as road construction and pothole repairs. Electrical construction refers to a turnkey solution from initiation phase to final handover of electrical construction services such as energy efficient installations, power line and substation construction, cabling and switchgear and electrification services.

Logistics Services offers road transport, material handling and consolidation, warehousing, full scope waste management and road logistics services. These encompass the transportation of plant and auxiliary components to remote sites, the removal of both general and hazardous waste, as well as the haulage of all heavy and abnormal sized equipment. With the largest multi-axle fleet in the Southern hemisphere, Logistics Services has the capacity to transport anything between 0 – 500 tons.

Building a lasting legacy
In answer to the challenge set by government to continually strive to uplift the economy of South Africa, Eskom Rotek Industries has achieved remarkable success stories in the communities we have operated in.

By 2017 Eskom Rotek Industries Construction Services electrified five rural communities in the Eastern Cape province for a total household connection of 1,800 households. The rural electrification included the construction of the electrification backbone infrastructure that included medium voltage lines (11-22kV), low voltage lines (230/400V), transformer installations and house connections. . Socio-economic development increased in these community areas which increased the realization of the ideal of long term sustainability.

Other legacy projects include the transportation of the enormous 828 meter high steal structure for the Burj Kalifa in Dubai (with Eskom produced fly ash mixed in the 45,000 m3 concrete foundation of this building); managing reliable water transfer from the Komati water scheme for decades; repairing 122,000 m2 potholes in one year and currently managing one of the largest road coal supply chains in South Africa.

The South African power utility identified Eskom Rotek Industries as its preferred turbine generator maintenance service provider with the result that we have been involved in outage maintenance and refurbishment on all South Africa power stations.

Looking towards the future
With the ever changing challenges presented by our macro and micro operating environs, Eskom Rotek industries will continue to investigate innovative methods and refine them into effective solutions to meet our client’s needs. While Eskom remains a major focus area for Eskom Rotek Industries, we can now expand the Eskom Rotek Industries footprint to include a diverse customer portfolio with tailor-made solutions to suit individual customer demands.

The product knowledge gained over more than a lifetime is of particular value and, like goodwill, needs to be shared in order for it to grow. We invite stakeholders in the energy, manufacturing, mining and oil and gas industries to contact us for future collaboration.  By building on the strengths that stood the test of time, Eskom Rotek industries can assist clients to develop new integrated solutions to business needs.

We look forward to strengthen relationships with new stakeholders in South Africa and the rest of the African continent. Visit us on or contact us on and let us partner with you.
