Water Holding Structures

With its ability to resist extreme hydrostatic pressure, Xypex has been used extensively to waterproof reservoirs for potable water, filtration plants, swimming pools, and aquariums.

Project Listing
  • Quingdao Olympic Sailing Center

    Qingdao, Shandong Province, China

    Qingdao Olympic Sailing Center located on Macau Road, Shinan District, was the sailing-competition venue for the Beijing 2008 Olympic Games. Initially, Xypex Concentrate was used to waterproof just the fire pool in the media center but its successful application resulted in Xypex being subsequently used to waterproof 20 pools, 2 elevator shafts, and 2 platforms. Xypex Concentrate was also used to waterproof the Four Seasons Hall in Qingdao Olympic Village.
  • Atlanta Water Program – Pumping Stations

    Atlanta, Georgia, USA

    Precision Concrete’s Patel notes that “particularly in the case of the Hemphill channel structure, we upped the Xypex dosage from 2 percent to 3 percent to enhance the crystallization process. That really saved us labor time chasing leaks and saved on injection costs as well. We saw continual healing progress until all the cracks dried up on their own. Now that we have some experience with Xypex we are already recommending it on other projects, including a world-renowned golf course in Georgia.”
  • Columbus Zoo Adventure Cove

    Columbus, Ohio, USA

    The Xypex Admix C-500 admixture used in the Adventure Cove pools crystallizes in the pores and micro-cracks, becoming a permanent and integral part of the concrete structure that will continue to waterproof and protect for the life of the pools. Admix C-500 not only permanently seals the concrete and can heal hairline cracks up to 0.5 mm, it also provides chemical resistance properties that mitigate the attack of chlorides, sulfates and the effects of carbonation and alkali-aggregate reaction.
  • Pairi Daiza Zoo

    Brugelette, Belgium

    Xypex Admix was critical in maintaining the water inside the enclosures and ensuring that there was no leakage into the hotel rooms. The concrete walls of these enclosures form a separation between the animal shelter and the rooms, so the guest has the feeling of being under water with the animals. While waterproofing was essential, chemical resistance was equally important due to the water containing chlorine that could potentially corrode the concrete structural reinforcing steel. Xypex’s Crystalline Technology ensured that the concrete was waterproofed, durable, and chemically resistant.
  • Puebla Michin Aquarium


    Despite being specified to use surface waterproofing, the owner and contractor decided that Xypex’s crystalline waterproofing technology was the best solution. Due to the fact that Xypex Admix C-1000 becomes an integral part of the concrete, the crystalline structure within the concrete prevents the ingress of water and other liquids even under strong hydrostatic pressure. 
  • Picayune Strand Restoration Project

    Collier County, Florida, USA

    Soon after completion, hydrostatic pressure caused the Merritt pump rooms, located 20 feet (6 m) below grade, to fill with water. The South Florida Water Management District (SFWMD) and its partner the U.S. Army Corps of Engineers chose to waterproof the concrete walls of the pump rooms with an application of Xypex Concentrate and Xypex Modified.
  • Residence Astoria

    Berges du Lac, Tunisia

    Xypex Admix was chosen as the waterproofing system for four suspended swimming pools in this luxury residential building. By resisting hydrostatic pressure Xypex Admix makes water-containing structures completely waterproof throughout the life of the concrete. Xypex Admix is added to concrete during mixing which considerably reduces the construction time of concrete structures.
  • Multibank 50 Building Panama


    Xypex Patch'n Plug and Xypex Concentrate were used to repair leaks and defects in the drainage channels and underground water tank of this building. Other attempts at repairing leaks caused by concrete placement issues and waterstop failure in construction joints had not stopped the leaking and, as the Resident Architect had used Xypex on previous projects, Xypex was chosen to provide a definitive solution to these leaks. Despite the high hydrostatic pressure, which was alleviated during application through the use of bleed pipes, the leaks were successfully and permanently repaired.
  • Ballarat Aquatic Centre

    Ballarat, Victoria, Australia

    Ballarat Aquatic Centre upgrade has been jointly funded by the Victorian Government Better Pools Program and Federal Government Better Regions Program. The new redevelopment will cater to 110,000 residents in Ballarat and surrounds. In conjunction with Burn Hamilton and Partners and M.L. Design Architects, Xypex Australia were able to assist with concrete waterproofing the new structure. Xypex Admix C-1000 NF and Xypex Concentrate were used in the new balance tanks, pools, pool concourses and wet areas.
  • Fitzroy Gardens Stormwater Harvesting Tank

    Melbourne, Australia

    Xypex Australia and 2Construct were involved in the installation of a 5 mega litre underground concrete water tank in the Fitzroy Gardens. This stormwater harvesting system will include full hydraulics to pump the water through a water treatment bed before it is stored in a separate tank to be used to water plants in the garden. Xypex Admix C-1000 NF has been used in all precast wall panels, tank base slab, and from panel to panel. Once complete garden beds will be planted on top of it so it is not visible from the gardens. Over 6,000 kgs of Xypex Admix C-1000 NF was employed in the construction.
