Penetron - Waterproofing in the hydroelectric industry | Apr 19, 2006 |
Two of the main challenges facing hydroelectric facilities are; A. coping with high hydrostatic pressure, which will lead to water penetration through the concrete and, B. the resulting corrosion of the reinforcement steel, which will cause deterioration of the concrete structure over time. The Penetron system offers a comprehensive solution to both problems; Penetron has been proven to dramatically increase the resistance of concrete to very high hydrostatic pressure (16 Bar for Penetron coating and 20 Bar for Penetron Admix). As the insoluble Penetron crystals fill up the cracks and pores, water penetration into the concrete is virtually eliminated.

Penetron prevents corrosion of reinforcement steel
Steel will not corrode in alkaline environments, hence it can be safely used in concrete under normal conditions. However, once the alkalinity at the steel’s surface drops below pH 8, the reinforcement steel will become de-passivated and corrosion will start. With the alkalinity of cured Penetron being around pH 11.5 and the presence of Penetron components both at the surface and throughout the concrete matrix, Penetron will help to maintain a highly alkaline environment and hence protect the reinforcement steel from corroding, and the concrete structure from deterioration. Penetron has been used on a multitude of hydroelectric projects, including The Glen Canyon Dam in Arizona, USA, Kiambere Hydroelectric in Kenya, Daugava Dam in Latvia, Long Tan Dam in China, Hao Binh Dam in Vietnam etc.
