The Issue: Natural Corrosion
How does corrosion develop in a water tank?
Any coating – even one that’s been applied perfectly – has a porosity that allows the oxygen present in water to come into contact with the metal wall and cause oxidation. The coating may undergo localized disbondment as a result of rust and lead to bare spots. Corrosion accelerates in these already-exposed areas, which ultimately creates perforations in the walls and leaks.
Repair: Vessels
CORROFIX™, a simple fix
The CORROFIX™ solution makes it possible to intervene directly on the areas with corrosion and to seal the leaks, no matter the type of vessel:
BEFORE
AFTER
Non-Pressure Vessels
Sand Filters
The advantage of our sand filter solution is that application is done without removing the filtering medium and welding is not required. After preparing the surface, our technicians apply a sealing compound and Kevlar® material to reinforce the repaired area.

Heated Pressure Vessels
Hot Water Heaters & Water Storage Tanks
Since repairing a hot water heater is oftentimes more economical and simpler than replacing it, our solution entails welding patch panels, repairing the shell, and replacing manholes.
Prevent: Impressed Current Cathodic Protection (ICCP)
CORROFIX™, reverse the natural flow of corrosion to stop it at the source
Oxidation is a natural electrochemical phenomenon. The oxygen dissolved in water captures electrons from the metal it comes into contact with, producing a natural corrosion current. Our ICCP solution gets to the heart of the problem. By generating a current and injecting it into the system in the opposite direction, CORROSTOP™ provides the oxygen with the electrons it would otherwise take from the metal.
The current is injected into the water via non-soluble anodes installed directly inside the tank. It then flows towards the metal walls requiring protection, transforming it into a giant cathode thanks to the electrochemical circuit created.
4 Elements Form the Impressed Current Cathodic Protection Circuit
1
Cathode
The surface requiring protection
Titanium Anodes
Diffuse the current in the tank internals
3
Direct Current (DC) Generator
Injects and regulates the current inside the tank
4
Reference Electrode
Monitors whether or not immunity potential has been reached
