Waterproofing protects structures against water infiltration which can cause expensive and irreversible damage. It is mostly invisible after construction is completed. Every day the basement of a building, or the outermost layer of a tunnel, is exposed to intense fluctuations in moisture levels and temperatures, all contributing to its deterioration. Count on Sika to provide long-lasting waterproof systems to protect your project.

100 years
