Contractor Support
For civil contractors, pipe contractors, and infrastructure teams that need experienced lining support in the field.
What is Hydrakrete-61?
Hydrakrete-61 is Hydrastone’s proprietary cement-based lining material developed for potable watermain and large pipe applications. Designed to bond to steel and concrete surfaces, it creates a durable protective lining that supports corrosion resistance, potable water safety, and long-term infrastructure performance.
Because we developed Hydrakrete-61, we understand how it performs in the field and how to apply it with precision. Our specialized technicians can support everything from full lining restoration to localized joint, seam, patch, and repair work, with the flexibility to apply the material by hand or machine depending on the project conditions.
-
Hydrakrete-61 is certified for use in systems that carry drinking water, giving contractors and project teams confidence that the lining material meets recognized potable water safety standards.
-
Hydrakrete-61 is designed to align with industry standards used in watermain and large pipe infrastructure work, helping contractors meet project requirements and specification-driven scopes.
-
The material is designed to adhere to common pipe substrates used in large water infrastructure, creating a protective cement lining along the interior surface of the pipe.
-
Hydrakrete-61 can be applied in different ways depending on the project, pipe size, access conditions, and repair scope. This makes it practical for larger lining applications, localized repair work on site, and more flexibility in solving complex problems.
-
Beyond full lining applications, Hydrakrete-61 can be used in specific areas where protection or restoration is needed, including pipe joints, seams, damaged lining areas, and localized repairs.
-
Once applied, the cement lining helps separate potable water from the pipe wall and supports long-term protection against internal corrosion, helping extend the service life of the pipe system.
Cement mortar lining has been used in watermain applications for generations because it provides durable corrosion protection in potable water environments. It remains one of the most trusted methods for lining large pipe and watermain systems because it is proven, practical, and well-suited to long-term infrastructure performance.
Unlike a surface coating that only acts as a barrier, cement mortar lining protects the pipe through both physical coverage and beneficial chemical interaction at the pipe surface. The cement lining helps create an alkaline environment at the steel interface, supporting passivation and reducing the risk of internal corrosion.
Why cement mortar lining is most trusted for watermains.
The advantage of autogenous healing.
Cement mortar lining has a natural ability to tighten and re-bond fine cracks once the pipe is back in service.
Autogenous healing is one of the key reasons cement mortar lining remains trusted in potable water infrastructure. Once a cement-lined pipe is placed back into service, the lining absorbs moisture, tightens against the pipe wall, and can naturally help fine cracks close and re-bond over time. This allows cement mortar lining to perform differently than many rigid barrier coatings, supporting long-term protection in wet watermain environments.
