Protectosil® BHN

The main deterioration mechanism for concrete decks is corrosion and scaling due to deicing products. Protectosil® BHN is eco-certified and penetrates deeply into the building structure to provide long service life even on wearing surfaces. Because it does not change the skid or slip resistance of concrete, it is ideal for driving surfaces like parking and bridge decks.

The spectacular Ala Moana Shopping Center in Honolulu, Hawaii, is the world’s largest open-air shopping center with more than 350 shops and restaurants to discover. The parking decks got a hydrophobic treatment with Protectosil® BHN, providing excellent protection against dirt, stains and scaling.

The Container Terminal Zeebrugge is located directly at the open sea in Belgium. The port is one of the most modern in Europe. The quay wall of the container terminal, continuously exposed to the salt water, is protected with Protectosil® BHN, increasing its expected lifetime significantly.

Railroad sleepers that are frequented day in, day out by railroad cars have to carry heavy loads. Additionally, the daily contact with water leads over the years to cracks weakening the concrete ties underneath the tracks. Protectosil® BHN helps protect the investments by preventing the ingress of water, thus maintaining the concrete blocks.

The 18 km long Storebaelt Bridge construction, comprising two bridges and a tunnel, crosses the Great Belt and connects the eastern part to the western part of Denmark. Weather conditions due to the harsh sea climate makes protection from the elements and the ingress of water indispensable. Protectosil® BHN shields the structure sustainably.

A clear, penetrating, breathable VOC-compliant surface treatment for use on concrete. The unique 100% silane treatment (no solvent) penetrates the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. Creates a deep hydrophobic layer that prevents water and water-borne contaminants from entering the substrate and causing premature deterioration. By combining low surface tension with a tailored rate of reaction, Protectosil® BHN is able to move through the moisture boundary layer that lines the pore structure of the substrate. This permits the development of uniform gradient permeation — a consistent level of protection throughout the entire depth of penetration — allowing for longer treatment life, especially on wearing surfaces.

Main benefits

  • Low VOC
  • Low-temperature application (20°F)
  • Low-temperature application (20°F)
  • Excellent long-term chloride screening on wearing surfaces (bridge decks, parking decks)
