Cementing

Turning Cement into a Water-Repellent Material

Cement is a key factor in construction. Processed into concrete, it can be found in almost all types of buildings. To preserve these buildings for as long as possible, they must first and foremost be protected against moisture penetration. This is achieved using silanes, which give the building material a water-repellent effect. With PROTECTOSIL®, Evonik has developed such a silane-based product for the construction industry. Thoroughly mixed into cement, it is distributed homogeneously throughout the entire matrix of the building material and makes it hydrophobic. The building structure remains breathable, but penetrating moisture no longer causes any damage. The same applies to reinforced concrete, where PROTECTOSIL® surrounds the steel with a passivating layer and thus protecting it against corrosion. Maintenance measures can be significantly reduced.
