Transco: Tank Lining
- The project was unusual, as the material had to be applied underwater.
- It rained solidly throughout the entire project.
SolutionWe commenced the refurbishment works by high pressure jet washing the surface with a biodegradable degreaser. A floating pontoon was placed into the channel to stop debris falling into it. We then lightly shot blasted the surface of the brickwork and coping stone to remove any further surface contamination and to create a strong mechanical key on which to apply the sealing system. The entire area was jet washed again to remove any splash contamination.
The area was then rendered with a special render mix and a water tolerant primer coat was applied. Once cured, we applied two coats of water tolerant and chemical resistance main coating. The top coat was grey to blend in with the body of the tank.
