Dam & Irrigation
Preserving Structural Integrity of Dams
The long-term structural integrity of dams and irrigation systems depends on keeping moisture from contacting the steel reinforcement. Inadequate waterproofing, cracks, failing joints, biochemical attacks, alkali aggregate reaction and abrasion are problems often found in this challenging environment.
Deteriorating concrete can lead to water loss, reduction in water flow and expensive unplanned maintenance. Failing or compromised dams and irrigation systems can even threaten public safety and environmental quality, so it is critical to protect and maintain them. Whether specified for new construction, or used for repairing and rehabilitating dams and irrigation systems, Xypex Crystalline Technology blocks water ingress into the structure and extends the life of these critical structures.
Pinheiros Sewage Pumping Station
Xypex Bio-San C500 was selected due to its ability to permanently waterproof the concrete and increase the structure’s resistance to sulfates and sulfuric acid attacks while preventing the growth of the bacteria that causes MIC.
Glass City Metropark
The concrete producer, Kuhlman Corporation, collaborated with Xypex to find a suitable waterproofing system for the below-grade utility vault. After evaluating various products and applications, Xypex Admix C-500, a specialized crystalline waterproofing admixture, was selected over traditional membranes.
Michigan Avenue Harrison Road Sewer Improvement
Xypex Bio-San is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with levels of H2S that cause microbial induced corrosion (MIC). Bio-San combines potent antimicrobial protection along with the unique crystalline technology of the Xypex Admix C-Series.
Erdenet Settling Tanks
Erdenet Mining Corporation SOE, situated in the northwestern region of Mongolia, is Asia's premier copper ore mining and processing facility and ranks as the world's seventh largest. This extensive complex processes more than 26 million tonnes of ore, yielding approximately 530,000 tonnes of copper concentrate and around 4,500 tonnes of molybdenum concentrate annually.
West Gate Tunnel
Engineers were concerned about potential adverse effects of carbonation from vehicle emissions on the concrete infrastructure for the West Gate Tunnel project. The general contractor conducted tests on concrete treated with Xypex Admix C-500 and found that the Xypex-treated concrete reported a carbonation effect depth of 0 mm. As a result it was decided to add Xypex Admix C-500 in the concrete for the exhaust ducts to permanently waterproof, enhance durability, and provide resistance to carbonation throughout the concrete's lifespan.
