Tile and natural stone coverings on balconies and terraces must be much more resistant than other covering surfaces, as they are exposed to frost, rain and solar radiation over the long term. Even the slightest damage can cause water to penetrate the structure, be absorbed by the mortar and be stored. Efflorescence and frost damage are the result.

The bonding mortar is the most vulnerable element in this system. This is why Saint-Gobain Weber has focused on the tile adhesive, in particular in this application. A watertight tile adhesive that can also be used as a bonded waterproofing offers maximum safety and significantly reduces the risk of damage.
