The science behind longer-lasting potable water infrastructure.
CSA/NSF-61 certified cement linings developed, manufactured, and applied by Hydrastone.
Hydrastone manufactures and distributes two proprietary cement-based lining products for potable water applications: Alkrete and Hydrakrete. Both are certified to CSA/NSF-ANSI 61 standards and engineered to protect drinking water systems from corrosion, contamination, and premature lining failure.
What makes Hydrastone different is that we do not simply install lining products — we develop them, manufacture them, certify them, supply them to tank manufacturers and specialty applicators, and apply them in the field ourselves. That gives our clients a direct connection to the technical expertise behind the material, not just the labour required to install it.
Whether we are restoring the internal lining of a domestic hot water tank, supplying material to a tank manufacturer, completing a potable watermain repair, or supporting a long-term maintenance program, Hydrastone brings product knowledge, field experience, and concrete lining science together in one place.
Alkrete:
Potable cement lining for hot and cold water storage tanks
Alkrete is Hydrastone’s CSA/NSF-ANSI 61 certified potable cement lining designed for hot and cold water storage tanks. It is one of North America’s leading cement lining materials for domestic water tanks and is used by tank manufacturers, specialty lining applicators, and Hydrastone’s own field teams.
Engineered to bond to steel surfaces and provide long-term corrosion protection, Alkrete helps restore the protective barrier inside potable water storage tanks. It is especially trusted for domestic hot water systems, where internal tank linings are exposed to demanding operating conditions over time.
Because Hydrastone manufactures Alkrete and installs it in the field, clients benefit from true product expertise at every stage — from assessing the condition of the existing lining to preparing the tank surface, applying the new cement lining, inspecting the finished work, and planning ongoing maintenance.
Best suited for:
Hot water storage tanks, cold water storage tanks, domestic potable water tanks, fire water tanks, tank relining, tank restoration, and manufacturer-applied cement linings.
Hydrakrete:
Potable cement lining for watermains and repair applications
Hydrakrete is Hydrastone’s high-performance cement lining developed specifically for potable watermains, pipe lining, seam lining, patching, and repair applications. It is certified to CSA/NSF-ANSI 61 standards and designed to meet AWWA requirements for freshwater infrastructure.
Hydrakrete was created to give engineers, municipalities, contractors, and infrastructure owners a certified cement lining option for potable watermain work where water safety, corrosion protection, adhesion, and field performance matter. It can be hand or machine applied and is suitable for steel and concrete surfaces.
For clients, Hydrakrete provides the confidence of working with a material developed by the same team that understands how it performs in real-world field conditions. Hydrastone’s expertise covers the full process — product selection, application method, repair strategy, inspection, and long-term protection of potable water infrastructure.
Best suited for:
Potable watermains, large diameter pipes, pipe lining, seam lining, patch and repair work, freshwater infrastructure, municipal applications, and contractor-supported watermain projects.
Why use cement mortar linings?
A proven, corrosion-resistant lining system that protects steel from the inside out — and can even help repair itself over time.
Cement mortar linings are trusted in potable water tanks and watermains because they do more than form a protective barrier. High-density cement helps limit the movement of water and oxygen to the steel surface, while raising the pH at the substrate to support natural steel passivation — a process that helps inhibit corrosion.
Unlike epoxy or glass-lined systems, cement mortar does not rely on perfect adhesion or a completely continuous coating to remain effective. A moist environment actually supports its performance, and if small cracks or voids develop, cement mortar can self-heal through autogenous healing and calcification. It is also easier to repair in the field, often with minimal preparation and less downtime.
For critical potable water infrastructure, cement mortar lining offers a durable, proven, and cost-effective solution designed for long-term corrosion protection in real-world wet environments.
