Façade Waterproofing

During its lifetime a building Façade is subject to the effects of thermal and structural movements as well as wind and water, all under a wide range of temperatures and climatic conditions. These stresses and movements subject the waterproofing to a range of demands; it needs to be strong, elastic, weatherproof and resistant to industrial, polluted atmospheres. It needs to give a service life as long as the life of the building, with no loss in performance or properties. GASE Façade waterproofing systems provide engineered waterproofing systems meeting all these requirements.
