Wastewater Treatment & Collection Structure Projects 

Xypex products play a key role in the prevention and treatment of problems common to the sanitary sewer collection system and the wastewater treatment plant.

Project Listing
  • AASS Wastewater Treatment Plant

    Entre Rios, Ecuador

    The walls of this plant were cast using the Machihembrado method. Because of this approach, Xypex Dry-Pac and Xypex Patch'n Plug were required to seal the construction joints. The same Xypex treatment was used on 518 m of cold joints and cracks. After these structural defects were repaired, the surfaces were treated with a two-coat application of Xypex Concentrate.
  • Alegria Wastewater Treatment Plant

    Rio de Janeiro, Brazil

    Xypex Concentrate and Modified were spray-applied to all foundations walls and slabs of this wastewater treatment plant to waterproof and protect it.
  • Bahr Dar Air Force Camp

    Bahr Dar, Ethiopia

    A two-coat application of Xypex Concentrate and Modified was used to repair and waterproof the interior surface of the swimming pool, water reservoirs, and six chamber septic tanks. Patch'n Plug was used to repair the poor quality concrete that was full of voids and honeycombing. A total of 3,940 kg of Xypex Concentrate, 2,350 kg of Xypex Modified and 1,330 kg of Xypex Patch'n Plug was utilized.
  • Bailonggang Wastewater Treatment Plant

    Shanghai, China

    All internal concrete faces of the eight digesters were treated with Xypex Concentrate. In areas where anaerobic activity and a highly aggressive chemical environment were anticipated, an acid-resistant lining was applied. However, the designers specified that Xypex also be applied to these specific areas as well, not only to provide secondary protection for the concrete but also to enhance the performance and durability of the primary acid-resistant lining.
  • Barbados Hilton

    Bridgetown, Barbados

    Xypex Admix was blended into the concrete mix and used to waterproof and protect the swimming pools, sewage clarification tanks and basements of this new hotel.
  • Blue Plains Wastewater Treatment Plant

    Washington, DC, USA

    The slurry wall sections are over 30 ft. deep and 18-in. wide. The concrete, designed to be flowable, incorporates pea gravel as the aggregate. The wall forms were filled with water at the time of the pours and then the water was displaced as the concrete filled the cavity. The project used Admix C-500 in soluble bags for just over 15,000 cubic yards of concrete.

    The completed system addition, to be operational in 2015, brings a 1930’s facility into the 21st century.
  • Bogotá Wastewater Treatment Plant

    Bogotá, Colombia

    This is the first of three Bogotá wastewater treatment plants to be treated with Xypex products. Xypex Patch'n Plug was used to repair defects and stop water leakage in the concrete before application of the coating system. More than 5,000 kg of Xypex products was used in the concrete waterproofing process.
  • Boston CSO Project

    Boston, Massachusetts, USA

    Prior to project start-up, CSI installed mechanical mix equipment that allows the concrete mix crews to monitor and quality check the quantity of Xypex Admix added to each pre-cast box. As the concrete cures, Xypex permanently seals the box to prevent the flow of liquids from the outside in, and the inside out. Time of manufacturing to shipping was cut from 30 days to less than 10.
  • Budva Wastewater Treatment Plant

    Budva, Montenegro

    A two-coat treatment of Xypex Concentrate was used to waterproof and protect the machine room in digester tank.
  • Calistoga Wastewater Treatment Plant

    Calistoga, California, USA

    A two-coat treatment of Xypex Concentrate and Modified was used to waterproof and protect the digester tanks as part of the upgrading of this wastewater treatment plant.
