Evonik solutions for Consolidation:
Historic buildings, statues and monuments are landmarks and tourist attractions, whose mineral building substance is extremely susceptible to weathering. Natural stone, sandstone, terracotta and bricks with their porous surfaces are easy gateways for moisture, wind, frost and snow as well as UV radiation. This leads to erosion, especially on reliefs and contours. Discoloration, flaking layers and efflorescence are more consequences of weather influences. So, important buildings and monuments are at risk of lasting damage.
Stopping and minimizing erosion
With PROTECOTSIL®, Evonik has developed a product group that provides reliable protection against erosion. The silane-based substances penetrate deep into the building material, thus providing longer-lasting protection than other methods. PROTECTOSIL® forms molecular bonds in the stone, which have a strengthening effect. Even extremely porous substrates can be solidified in this way. In addition, PROTECTOSIL® can be easily applied using standard spraying equipment. The agents do not change the appearance of the surface of historic buildings and monuments.
Cost and Benefit in good balance
PROTECTOSIL® ensures more durable historic building substance, minimizing restoration work and reducing costs. At the same time, it also protects new building fabric efficiently. With PROTECTOSIL®, cost and benefit are in a very good balance.
