What Hydrastone does

Hydrastone is a privately held Canadian specialty services and materials company that inspects, maintains, repairs, and relines domestic hot water storage tanks, primarily for commercial and institutional buildings such as condominiums, apartments, hospitals, hotels, universities, airports, and sports arenas. Founded in 1993 by Jamie Russell and headquartered in Guelph, Ontario, the company operates regional field offices in Toronto, Vancouver, and Calgary, and self-identifies as Canada's largest player in domestic hot water tank relining, repair, and maintenance.

The company's core technology is its proprietary cement-based lining system. It manufactures Alkrete, a CSA/NSF-ANSI 61 certified potable water cement lining used both by tank manufacturers at the factory stage and by Hydrastone's own field crews when restoring tanks in service. It also manufactures Hydrakrete and Hydrakrete-61, similarly certified linings designed for potable watermain and large-pipe rehabilitation to AWWA standards. This vertical integration from material formulation through field application is a defining feature of the business.

Hydrastone generates revenue through two channels. The primary stream is professional services sold directly to property managers, building owners, and facility teams, including tank inspections, anode replacement, sediment removal, weld repairs, and full relining, all priced on a quote basis following a free initial tank assessment. The secondary stream is product sales and distribution of Alkrete and Hydrakrete to tank manufacturers and specialty applicators across Canada and the United States. Recurring maintenance contracts (with anode replacement recommended approximately every two years) and condition-based inspection reporting drive revenue stickiness, while the company's educational content marketing and regional sales presence support customer acquisition.

Revenue model

1. Tank Inspection Services: Provides inspection services for domestic hot water tanks including exterior and interior assessments, corrosion depth measurements, and written condition reports. This is a service-based revenue stream that drives upsell opportunities for maintenance and relining services.
2. Tank Maintenance and Repair: Includes anode replacement, fitting repairs, sediment removal, weld repairs, gasket replacement, and minor lining patches for domestic hot water tanks. Recurring maintenance services that help extend tank service life.
3. Tank Relining Services: Full interior relining of domestic hot water tanks using Alkrete cement lining. Restores the protective barrier to factory condition. Can often be completed in a single day at a fraction of the cost of tank replacement.
4. Product Sales (Alkrete and Hydrakrete): Manufactures and distributes proprietary cement-based lining products to tank manufacturers, specialty applicators, and field teams. Supplies lining materials for both hot water tank and watermain applications across Canada and the United States.
5. Watermain and Large Pipe Lining Services: Provides cement lining services for potable watermains, large diameter pipes, joint work, and repair applications using Hydrakrete-61. Supports contractors, municipalities, and infrastructure teams.
