Concrete Waterproofing by Crystallization™
The City of Terrebonne, Quebec, recently modernized its infrastructure with a new water treatment plant to improve water quality. To ensure long-term durability in harsh sewage environments with high H₂S levels that cause microbial-induced corrosion (MIC), the project incorporated Xypex Bio-San—a specialized admixture designed for integral concrete protection.

The Bardy Pool rehabilitation project in Québec upgraded the municipal pool to meet modern safety, hygiene, and accessibility standards. To ensure long-term waterproofing and durability in a chemically aggressive environment, Xypex Admix C-500 was added to the concrete mix. This integral crystalline solution protects against water penetration, hydrostatic pressure, and chemical attack while offering self-healing properties for minor cracks. The result: a cost-effective, sustainable solution that enhances the pool’s performance and longevity.

Xypex products prevent freeze-thaw damage in concrete by forming a permanent, non-soluble crystalline structure that blocks water ingress, the primary cause of such damage. This crystalline technology seals capillaries and microcracks, preventing moisture-induced expansion during freezing and thereby increasing the concrete’s durability and lifespan. Unlike traditional membranes, Xypex becomes an integral part of the concrete, offering long-term protection, self-sealing capabilities, and versatility across various cold-climate applications, all while being non-toxic and environmentally friendly.

The iconic 345,000-gallon Neptune Pool at Hearst Castle, California, leaked for most of its 90-year history. During the 2014 drought, a four-year, $10 million restoration began, including new filtration systems, leak repairs, and waterproofing. Xypex Crystalline Technology played a key role—patching defective concrete, applying Xypex Concentrate, and creating a permanent crystalline seal within the concrete. Today, the pool is leak-free for the first time, preserving this historic landmark for over 750,000 annual visitors.
