Wetlock's 'Retank' system has a 100% success rate!

The 'Retank' system involves:

- Pump out of the tank
- High-pressure water-blast all internal walls and floor
- Wet-vac and wash clean
- Application of a new concrete skin to the internal surfaces
- Special treatment including flexible reinforcing of all wall and floor cracks
- Application of 'Potable Water Approved' membrane (AS-4020) in a multi-coat process
- When cured, the tank is rinsed and final

The images are an example of a tank repair project. The tank is inbuilt beneath a luxury home, where two of the walls were leaking into adjacent living spaces - preventing the sale of the home.

Following draining and a thorough inspection, it was revealed the cause of the leak was a result of poor application standards, particularly the lack of priming prior to the application of the membrane. Since completion, no further leaks have been reported.

The 'Retank' system is more affordable than installing a new poly tank and allows you to preserve the benefits of owning a concrete tank.
