Maintenance of THE VALUABLE BUILDING STRUCTURE 

Evonik offers tailor-made Protectosil® silane-based building protection systems for hydrophobation, graffiti and surface protection, corrosion control and stone consolidation. The main reason for the deterioration of structures is the ingress of humidity, efflorescence or damaging by de-icing salt or salt-wedging. The key to successful protection of valuable building structures is to stop water and chloride ions from entering into the substrate.

We not only look back on many references in the area of corrosion control. We even have the suitable product defending the building material against pollution, infestation of alguae, mold, moss and graffiti in our portfolio.
