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. This makes it possible to extend the useful life of buildings with a simultaneous reduction of maintenance and energy costs.
The tower walls of the impressive Moyland Castle in Germany and the world's largest collection of Joseph Beuys' works in the castle museum are protected with Protectosil® against the ingress of moisture.
Protectosil® products extend the service life of our public infrastructure. Especially in the case of bridges and roads that must be financed by public funds, is a real need for restructuring requirement. The bridge piers of the 36 km long Hangzhou Bay Bridge in China are treated with the corrosion inhibitor Protectosil® CIT which effectively repels water and pollutants.
Evonik Resource Efficiency has developed a series of Protectosil® products, designed to meet the particular requirements in the area of hydrophobation. The excellent water beading effect is shown on the left side of the building material which was treated with Protectosil® water repellents.
Protectosil® protects the structure of the 67-meters-high roof of the world-famous Syndney Opera House in Australia, thus preventing deterioration by humidity rising from the sea.
Water, road salt, and heavy traffic put a strain on the steel-reinforced concrete used in bridges. Protectosil® from Evonik 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.

Maintenance of THE VALUABLE BUILDING STRUCTURE
Evonik offers tailor-made Protectosil® silane-based protective systems in terms of water repellents, antigraffiti, corrosion control, surface protection and stone consolidation. However the main reason for deterioration is the penetration of humidity, efflorescence or damaging by de-icing salt or salt-wedging, for example on the metal parts of bridges, that become noticeable as corrosion.
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.
