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. 
  • American Furniture Manholes

    Texas, USA

    The design team was looking for corrosion protection for the manholes and chose Xypex Bio-San C500 over the alternate antimicrobial admixture. Xypex Bio-San C500 was chosen because it provides the precast sewage elements with protection against microbial induced corrosion and aggressive chemicals, as well as waterproofing and crack healing properties. The precast manufacturer reported that there were no operational or fabrication issues associated with including Xypex Bio-San C500 in the wet cast mix.
  • Bahr Dar Air Force Camp

    Bahr Dar, Ethiopia & Djibouti

    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. Xypex 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.
  • Becici Wastewater Treatment Plant

    Becici, Budva, Montenegro

    Xypex Concentrate and Patch'n Plug were used for the repair and rehabilitation of this wastewater treatment plant. Prior to the use of Xypex, there was severe leakage into all tanks and negative hydrostatic pressure. The WWTP tank is situated on the bank of the Adriatic sea and under the sea level -7. Xypex has successfully stopped this leakage.
  • Blacklick Creek Sanitary Interceptor Sewer

    Columbus, Ohio, USA

    “The addition of Xypex Admix to protect precast concrete structures such as tunnel segments is a great example of how projects can offsite certain construction steps and save time and labor,” says Bradford-Dice. “Xypex Admix not only replaces other types of waterproofing such as membranes and coatings, but also provides protection against microbial induced corrosion so common and potentially damaging in sewer structures.”
  • Blue Plains Wastewater Treatment Plant

    Washington, DC, USA

    The slurry wall sections are over 30-in. 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 Xypex Admix C-500 in soluble bags for just over 15,000 cubic yards of concrete.
  • 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. More than 5,000 kg of Xypex products was used in the concrete waterproofing process.


  • 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.
