ISG Profile

The Infrastructure Specialist Group (ISG) was formed in 2013 after three leaders in the manufacture of infrastructure and mining products merged. Technicrete, Rocla and Ocon are prominent brands well known in the industry. They were previously owned by Murray & Roberts which sold them as a result of the group focusing their growth aspirations in engineering, mining and construction. The three companies were acquired by a consortium consisting of private equity firm Capitalworks, RMB Ventures, Pan African Group and senior executives within the companies, which led to the formation of the company ISG.


ISG is proud to be a South African company. This fuels our devotion and commitment to the sustainable development of our region and its people. We have made, and will continue to make a meaningful contribution through infrastructure and related products to improve the lives of the people in South Africa and neighbouring countries.
