BRAITHWAITE TANK LINING - SOUTH WALES This Braithwaite water tank had been leaking for some time. Our client had been welding patch repairs over the leaks from the outside to good effect. But this practise was becoming impracticable and they wanted a repair system that would last for at least the next 20 years. 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 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.
