Inca Masonry Products (INCA), registered as Garden Architecture (Pty) Ltd, had its origin in Berlin Concrete, in 1981, and later as Border Concrete & Engineering. Murray and Robert’s Blue Circle Cement Division acquired the company in 1988. A management buy out saw Inca sold to W J Breitenbach and J K Drake in 1977, prior to Murray & Roberts selling the Blue Circle Group of Companies to the French company Lafarge.

A BEE Group acquired INCA in July 2005, lead by Mr Zolile M Tini – Managing Director and shareholder. Other shareholders include Ms B T Gabelana and the National Empowerment Fund.

INCA’s reputation for the manufacture and delivery of quality products and exceptional service has been earned largely through its active involvement in supplying materials to various government subsidised housing projects, dealing directly with developers.

This concrete retaining wall system is durable, long lasting and provides structurally sound solutions for a wide range of site conditions. The typical size of the INCA Concrete Retaining Block units facilitate the construction of walls in remote and difficult to reach locations, as well as the construction of complex curves and other architectural layouts.

This multipurpose walling system overcomes the problems associated with building on unstable ground as the pilaster block allows for the wall to accommodate ground movement without cracking. The pilaster also acts as a profile for setting out of corners and block courses, allowing for the wall panel to be erected by workers with limited skills. In addition the pilaster can be filled with concrete and reinforced, if required.
