For more than 100 years, Sika has been producing high quality, innovative technologies for concrete. Sika’s first product, Sika 1, was a concrete admixture that allowed for the electrification of tunnels in Europe by waterproofing the concrete that lined the interior. Now recognized as a world leader in specialty chemicals and other products specifically engineered for concrete, we continue to bring technologies to the market that focuses on the optimization of costs and durability of concrete.
