Raubex was founded by Koos Raubenheimer in November 1974.The first contract was awarded to it by the Free State Provincial Administration to construct a bridge over the Vetriver near Bultfontein. The Company therefore started off as a concrete structures contractor. The developing road network required an increasing number of bridges and Raubex was there to build them.
1975 – 1986
During the next years until 1986 the Company started to diversify into road construction and crushing. In this period Raubex completed 109 projects which included 50 bridges. Raubex took on its first major road construction project, namely the construction of the Kroonstad to Koppies road.
1987 – 1996
From 1987 onward the Company would take on larger road construction projects and would start venturing outside its original playing field namely the Free State. From 1987 to 1996 the completed projects increased to 200.
1996 – 2006
During 1996 a process of unbundling helped strengthen the competitive spirit and would help Raubex through tough years, when infrastructure spending was at a low. During 2004 the process was reversed and the Company consolidated into the current three divisions. During this period the Company showed rapid growth in the road rehabilitation sector.
Raubex listed on the Johannesburg Stock Exchange on the 20 of March 2007. Since becoming a public company Raubex has grown annual revenues by 285% to R4.5 billion.
