Protectosil® for bridge decks
Protectosil® protects the infrastructure of bridges
Infrastructure projects, such as bridges, can especially benefit due to reduced need for future roadwork, which results in less traffic and cost to maintain the structure. Bridges, especially the deck surface, are subjected to harsher conditions than other building structures.
The Commodore Barry Bridge, New Jersey, is protected with Protectosil® CIT, extending the lifetime of the steel-reinforced concrete structure, meaning lower costs.
Particularly under harsh weather or environmental conditions, penetrating water can trigger damage. The 7,000 bridge piers of the Hangzhou Bay Bridge in China, firmly embedded in the bottom of the sea, were therefore treated with 40,000 liters of Protectosil® CIT which repels effectively water and harmful contaminants.
Wind, weather, and traffic conditions both within and high above the sea create special challenges for operation and maintenance. The application of Protectosil® BHN protects the Storebaelt Bridge in Denmark against water-soluble contaminants and water to keep the traffic rolling.
Protectosil® CIT and Protectosil® DRY CIT
Heavy use of deicer salts, proximity to salt water, freeze-thaw conditions and vehicular traffic accelerate damage. High- performance products are necessary to combat these tough conditions. The scientifically proven corrosion control makes Protectosil® CIT the product of choice for suppressing the corrosion mechanism. It protects steel reinforced concrete structures like bridges against rust, increasing their service life considerably, right from the start. The virtually solvent-free corrosion inhibitor is also suitable for repairing structures that have already been affected by corrosion. Protectosil® DRY CIT is a solid mass modifier for corrosion protection of concrete. The product is easily dispersible, highly temperature stable, requires no special after-treatment and forms a water vapor-permeable barrier against water-soluble harmful substances. The cost of the protective treatment is not just the material price, but includes application labor, lane closure and retreat time. Protectosil® products for bridges are extremely cost effective, because:
Easy spray on application
Fast dry time
Can be applied down to 20°F/ -7°C
10+ years retreatment time
Protectosil® BHN, an eco-certified efficient water repellent can prolong structure service life by up to approximatively 100 years. Reduction of water uptake is important where weather and mechanical stress is high. Bridges have to endure harshest climatic phenomena. The product reaches very high penetration depth and is specially suited for the water-repellent impregnation of mineral construction materials in outdoor areas.
