Waterproofing systems protect structures against water infiltration which can cause expensive and irreversible damage. These systems are mostly invisible after construction is completed, but continue to protect the structure for the duration of their lifespans. 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's industry leading waterproofing systems to provide life-long protection of the structures on your project.

Sika has over
100+ years
of waterproofing experience, since the first Sika waterproofing product was invented in 1910.
3.3 million
square meters of Sikaplan® waterproofing membrane, equivalent to about 330 football fields, was used on the Gotthard Base Tunnel, the longest railway tunnel in the world.
