Waterproofing Façades

Cracks and fissures in façades result from differential ground settlements, thermal factors, materials incompatibilities, or weathering factors. The façade system and façade finishing are determining in ascertaining how a building is affected by inclement weather. It is easier for water to penetrate a porous surface. Water penetration damages aesthetics by causing cracks, stains, and fungus, as well as reinforcements accelerating structural deterioration processes.

Solutions for waterproofing natural stone facades include the removal of all joints between stones and their replacement and the filling of all joints around doors and windows.

For plastered facades, solutions based on watertight mortars and monocouche plasters are available, as well as highly elastic waterproofing coating with exceptional resistance to extreme weather conditions.

Anti-carbonation paints are also available with long-term protective and decorative properties to act as a barrier against the ingress of chlorides and carbon dioxide while allowing the passage of water vapor from the substrate.
