Braithwaite Tank Repair and Fibreglass Lining - South Wales

These pressed steel Braithwaite water tanks were starting to leak in places.

The sectional panel joints were leaking in this 'Braithwaite' water tank. Our client had been making welding patch repairs over the leaks from the outside. This practise was becoming impracticable and they wanted a repair system that would last for at least the next 20 years.

The original factory bitumastic coating was breaking down and the exposed internal steel surfaces were rusting badly.?

The tank was drained and inspected. It was found that the original factory bitumastic coating was breaking down and leaving the steel substrate exposed, ultimately causing the surfaces to corrode. Because of the condition of the tank is was decided to apply a reconstructive fibreglass lining covering the internal walls and floor.

The completed cured application was topcoated with a waxed polyester gelcoat/ flowcoat.

The internal surfaces were all keyed by sand blasting. The sand blast prep removed what was left of the original bitu coating. A specialist resin primer was applied to the cleaned surfaces before the repairs were made and the fibreglass lining system applied to the walls and floor surfaces.
