Process Water Storage Tank - Halifax This cold water storage tank wasn't leaking but as you can see needed refurbishment. The tank stood at over 8m high so we got the scaffolders in to erect safe working platforms around the internal perimeter. The confined space trained scaffolders made a great job giving us access to the walls. We sand blasted all the internal surfaces using a recycled glass as our blast media and applied a Lloyds approved fibreglass lining to the walls and floor. Giving a maintenance free finish that will last for at least the next 20 years.
