Description

CR 90 is used for waterproofing non-deformable, crack-free mineral substrates such as concrete, brick-work, renders and screeds. CR 90 works in two ways – it forms a waterproofing layer on the surface of the substrates and additionally, during the structure exploitation, it builds crystals in the substrate’s pores. This process leads in time to the complete closure of capillarity routes, which finally eliminates the water transport in the concrete, in both directions. CR 90 can be used for waterproofing of balconies, pedestals, underground parts of the buildings including basement walls, sewage treatment plants and water tanks (including drinking water tanks) with a water depth up to 15 m. It is also suitable for waterproofing small, monolithic swimming pools up to the size of 20m2.
