From humble beginnings in 1952 Oranje Mynbou Vervoer (OMV), started mining limestone in the Henneman area in the Free State. During its 68 years of existence, the company became a recognized industry leader and specialist in the supply of building and construction materials, including bulk agricultural and construction grade gypsum, ready-mix concrete and various construction aggregates.

This commitment to service excellence did not go unnoticed as OMV became part of the Raubex Group in June 2014. This transaction increased the company's access to capital which resulted in investments into state-of-the-art machinery and equipment currently being used at its six plants, including two crushing plants (North-West Province), three ready-mix concrete plants (in Stilfontein, Potchefstroom and Kimberley) and gypsum plant (in Potchefstroom)

OMV supplies various markets including agriculture, construction and interior design. Investments in technology mean increased efficiency (including the reduction of water content) resulting in more value for money for its clients. In-house Lab testing of materials is also done to ensure adherence to industry standards and customer specification.

OMV is dedicated to providing cost-effective products to the market in order to play its part in building safe, reliable and long-lasting infrastructure for Africa.
