For more than a century, Sika has been producing high quality, innovative admixture technologies for concrete. Sika’s first product, appropriately named "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 focus on the optimization of cost, workability, and durability of concrete throughout the production and placement processes.
