Tosas’ record in the development and supply of bituminous products to Southern Africa represents a collective of unmatched skills, experience, and know-how.

Its successful adaptation and game-changing innovations speak to the trust it has earned over more than 40 years. Deon Pagel, managing director, reveals Tosas’ new crumbed rubber technology (NCRT), which is set change the way roads are made.
