Protectosil® - Your partner for building protection

Evonik's Protectosil® products protect mineral undergrounds as concrete, granite, render or sandstone permanently against harmful environmental influences and pollution. Protectosil®, one of our best-known and longtime successful brands, prevents infrastructural buildings like bridges and tunnels as well as historical monuments from deterioration. Thanks to the protective treatment their service life is extended significantly. Maintenance and energy costs are reduced.

Water, road salt, and heavy traffic put a strain on the steel-reinforced concrete used in bridges. Protectosil® is a building protection agent that extends the life of important traffic arteries and can prevent potential damage before it can even take hold. The video shows, taking the state of German bridges as example, how Evonik's building protection products can counteract corrosion right from the start of construction.

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, mould, moss and graffiti in our portfolio.
