​Hydratight technicians, in collaboration with Henkel engineers, use a calculation and documentation tool to factor in all of the parameters of the pipework to determine the appropriate repair approach. Upon client review and approval of the documentation, the required materials and tooling can be quickly mobilized to the jobsite. Following strict quality program procedures, Hydratight technicians will prepare the pipe or component surface by grit blasting or wire brushing, cleaning the surface and applying a corrosion inhibitor. Next, superior metal is applied as a defect filler prior to applying the appropriate reinforcement that consists of multiple layers of resin and glass-carbon fibre tape. A sprayable or brushable ceramic coating can is then applied to create a top finish.

Two different solutions are available:
• Standard temperatures: Operating up to 176°F / 80°C (158°F / 70°C for B Repair)
• Elevated temperatures: Operating up to 266°F / 130°C
