Waterproofing is what protects your structure against water infiltration which can cause expensive and irreversible damages. 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. Sika has over 100 years of waterproofing experience, since the first Sika waterproofing product was invented in 1910.
