Dams & Irrigation Structure Projects 

Xypex products play a key role in the waterproofing of concrete against water leakage, even against extreme hydrostatic pressure. The unique Xypex technology also protects concrete against the effects of sulfate attack and crack or joint failure.

Project Listing
  • Abiquiu Dam

    Espanola, New Mexico, USA

    Xypex Concentrate and Modified were applied to the power house and gate operator building at this dam on the Rio Grande River in New Mexico. The Xypex products were specified by Tudor Engineering of San Francisco and the application was performed by personnel of Bechtel Construction Co., the prime contractor for the project.


  • Brana Grnčarevo,Trebinje

    Trebinje, Bosnia & Herzegovina

    The concrete handrail at the Grnčarevo dam was damaged by age and exposure to extreme elements. The engineers chose Xypex crystalline coatings to repair and protect the structure. One coat of Xypex Concentrate was applied to protect the existing structure by filling all the pores, capillaries and micro cracks to 0.40 mm. Xypex Concentrate was applied by airless spray 1 kg/m2, and 2,900 kg was used. The application was performed ABV Ltd. Trebinje.
  • Canal do Sertão - Hinterland Water Channel


    Xypex Crystalline Technology was introduced to the project as a means to solve a specific problem in the early stages of construction. As a result of its performance it became an important component of the whole project to solve the waterproofing challenges. The combined efforts of the federal government, the design team and the contractors together with technical assistance from Xypex distributor MC Bauchemie, enabled the timely delivery of these stages of this highly important project for the Sertão Nordestino region of Brazil.
  • Colibita Dam – Gatehouse


    Xypex products were used to waterproof and protect numerous areas on this dam’s gatehouse.
  • Dau Tieng Dam

    Tay Ninh, Vietnam

    After a successful trial in 1997, Xypex was specified and used to waterproof 400 m2 of the upstream discharge chamber of this dam. Xypex also supplied on-site technical support.
  • Gabcikovo Dam

    Gabcikovo, Slovakia

    Before repairing and waterproofing the entrances and corridors leading to the water locks of this dam, the concrete surface was first cleaned with a high-pressure cleaning unit. A two-coat application of Xypex Concentrate and Modified was then applied to the surface. Cracks and joints were filled and sealed with Xypex Patch'n Plug.
  • Grimsel Dam System

    Grimsel Area, Switzerland

    Xypex crystalline waterproofing was used at dam sites in the Grimsel area of Switzerland. Areas of application included 10 ton cable car station which is built into rock, tunnel sections (concrete and shotcrete), valve house, power house entranceway, freshwater reservoir, retaining walls, transformer stations, and machine rooms.
  • Harjavalta Hydroelectric Dam

    Harjavalta, Finland

    Xypex Admix was used in the hydropower plant’s restoration project to ensure water tightness of the concrete structure. 
  • Huaylacancha Dam

    Huancayo, Peru

    Xypex Patch'n Plug was used to repair cold joints after the parge coat was removed from the upstream and downstream faces of this dam. Both Xypex Concentrate and Modified were used to waterproof the upstream face while a single coat of Xypex Concentrate was all that was needed on the downstream face.
  • Ilda Dam

    Kasama, Japan

    Xypex products were used to stop water seepage through construction joints on the downstream face of this dam located in Ibaraki Prefecture. The photographs show the dam face before and after the Xypex application. The prime contractor for the project was Toda Gene Co., Ltd. and the Xypex application was completed during 1991.
