Tank lining for HydraStone began almost 20 years ago as a unique business that consisted of applying a specialty cement based lining to the inside of industrial sized Domestic Hot Water Tanks. At that time many companies in related industries were approached to fix or reline these tanks. Unfortunately, most contractors simply didn't know how to repair or replace the original cement liner from the factory installed many years earlier and in most cases caused more damage than good. Over the next 10 years, a team of professionals was formed to create HydraStone, including the first original tank liner in Canada, bringing with him a great deal of experience. After lining hundreds of tanks and inspecting a thousand more, it became obvious what works and what doesn't. The Alkrete Liner, with a 40 year history became our most sought after lining material and was eventually acquired by HydraStone in the 2005 and certified to CSA, NSF 61 standards.
