D E C E M B E R 2 0 2 0 | 15 Concrete As such, jurisdictions such as the City of Lathrop, California, specified Bio-San C500 for its River Island Sewage Pump Station as an alternative to highly expensive (and inferior) epoxy coating, as did companies such as Wolverine Engineers & Surveyors Inc.: it specified Bio-San C500 for the Village of Pinckney, Michigan's Force-Main and Pump Station replacement project. The product provided the required antimicrobial protection, and non-criti- cal areas of the wet-well not exposed to MIC were treated with Xypex Admix C-1000. Meanwhile, Kari Yuers, president and CEO of Kryton International Inc., reports that business is brisk and her company continues its efforts globally to educate end-users on the most effective ways to use her iconic admixtures. One recent project that benefitted from Kryton's expertise was Vancouver's River District, the new 130-acre neighbourhood being developed along the Fraser River in South Vancouver – and whose build- ings require effective waterproofing. The design team specified Krystol Internal Membrane (KIM) in the concrete mix for all the below-grade areas. KIM contains Krystol technology, which when added to concrete chemically reacts with water and un-hydrated cement particles to form insoluble nee- dle-shaped crystals. These crystals fill the concrete's pores and capillaries, and any moisture introduced through cracks in the concrete trigger crystalliza- tion and the self-sealing process. To complete their waterproofing system at River District, the project team used Krytonite Swelling Waterstop, Krystol Waterstop Treatment, and Krystol Waterstop Grout on the below-grade con- struction joints. Krytonite Swelling Waterstop is a synthetic rubber waterstop that uses swelling pres- sure to seal concrete construction joints and stop water (even contaminated water). Kryton has recently added wireless remote concrete monitoring to its Smart Concrete solu- tions: it is being used on projects such as the Grady Memorial Hospital expansion in Georgia, which had intense time commitments and thermal monitoring requirements. Given that other devices were unable to keep up with the scope of the expansion (they required staff to go on site to retrieve temperature data from foundation pile caps, for example), Fly & Form Structures Inc. relied on Kryton's Maturix sensors for real-time monitoring and simplified project management via a cloud-based platform. Kryton also worked with the contractor to custom- ize reports and helped incorporate all the data in a single spot, as well as provided extra sensors and answered technical questions. Finally, Brian Hall, managing director of the Canadian Precast/Prestressed Concrete Institute, says, "COVID-19 is transforming our built envi- ronment because of the fear of infection spread; therefore, architecture and urbanism during and after the pandemic will never be the same. "Could COVID-19 alter building techniques and should we adopt a more modular construction strategy? If so, will the future witness more prefab- ricated and standardized components?"
