Protecting Structures From Humidity And Rain

feature-top The Chao Phraya River Crossing Bridge in Thailand is protected with Protectosil® BHN and Protectosil® SC CONCENTRATE against corrosion and other harmful weathering and environmental influences like dirt, algae and moss.
The tropical–hot and humid climate in South East Asia might affect the facades or even the stability and safety of buildings. Evonik’s Protectosil® can extend significantly the lifetime of buildings by providing protection from water, oil and dirt ingress. Most importantly, the treatment with Protectosil® products reduces maintenance and energy costs. According to the ASHRAE Humidity Standards, the recommended humidity level for buildings is under 60 per cent. However, for tropical countries, particularly Thailand, the humidity level can be hovering around 90 per cent during summer. Buildings in countries, especially those, which are located by the seaside, will have to withstand the effects of high humidity. The formation of moss and algae on the facades of the buildings might cause structural damage. The penetration of water and dissolved salts from seawater might also lead to cracks and spalling. Bridges built across the seawater are especially threatened by corrosion. The steel will get rusty when water and salt penetrate the concrete, which could rapidly undermine the bridge’s stability. To increase the service life of the bridge, the Chao Phraya River Crossing

Bridge Construction Project in Thailand had decided to use Evonik’s Protectosil® from the beginning of its construction. Protectosil® is a unique building protection product that provides protection to the pillars against rain and seawater. The protection’s main element is the waterproof impregnation thanks to Protectosil® BHN. After applying this specific product onto the bridge’s concrete barriers, it will penetrate deeply into the concrete, where it forms a colourless, water-vapor-permeable coating and can effectively prevent water intrusion as well as corrosion into structural elements of the building. Acting like a breathable waterproof jacket, the product ensures protection and creates a dry and healthy climate inside. Besides that, it can also provide abrasion and UV protection, which makes it the perfect solution for outdoor concrete located at high traffic areas like the Chao Phraya River Crossing Bridge, where more than 46,800 vehicles are expected to cross over on a daily basis. Apart from protecting the building structure of the bridge, an additional product, Protectosil® SC CONCENTRATE, has also been applied to keep the surfaces of the bridge clean. Dirt, algae and moss can be removed easily without any residue from Protectosil® treated surfaces. Now with Protectosil® BHN and Protectosil® SC CONCENTRATE being applied onto the Chao Phraya River Crossing Bridge, the beauty of the bridge is maintained. At the same time, the products help sustain a more durable bridge with less structural risks like deterioration due to corrosion. Most importantly, costs can be minimized while simultaneously increasing the durability of the building structure.
