The seaside city of Largo needed a way to restore crumbling concrete at the heart of its wastewater treatment plant. In consultation with a local engineering firm, the city chose to restore the plant’s biological nutrient removal (BNR) ‘trains’ using the single-step Xypex Megamix II with Bio-San instead of a time-consuming multi-step alternative.
Xypex Crystalline Waterproofing was spray-applied to the interior of two large drop shafts at the heart of a new combined wastewater system in the Prague enclave of Ďáblice, saving more than two weeks of labor. Approximately 20,000 ft2 (1,900 m2) were treated to protect the two shafts from internal wastewater spray and external groundwater intrusion.
Fiber-reinforced Xypex Megamix II was used to repair and protect the flocculation and
sedimentation basins at the Mitchell Water Treatment Plant in Greensboro, North Carolina, USA. The cost to repair the structures was 5-10 times less than the cost to rebuild and is expected to provide up to 40 years of additional service.
The ambitious $368-million Atlanta Water Program has successfully converted a defunct granite quarry into a 2.4 billion gallon reservoir and extended the city’s drinking water reserve supply from a mere 3 days to more than 30. Xypex Admix C-500 was added to the concrete for two critical flow control channels in order to help the city meet its 100-year longevity goal for the new structures.
To stop active leaks and protect the cast-in-place concrete walls of the 223-foot deep lift station at the Lower Meramec WTP in St. Louis, a three-product system consisting of a base layer of Xypex Concentrate, a reinforcing layer of Xypex Modified and a final treatment of Xypex Gamma Cure — a curing accelerant and evaporation retarder – was applied as part of an extensive rehabilitation program.
Xypex Bio-San C500 is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with high levels of H2S that cause Microbial Induced Corrosion (MIC). Watch the animation to learn how Bio-San C500’s robust dual technology system eliminates the problem.
There are an increasing number of project delays with contractors placing great importance on worker safety and availability. Learn how companies are using an alternative proven technology to move concrete waterproofing off-site thereby reducing site-activity and accelerating construction schedules.
