COLD WATER STORAGE TANK REFURBISHMENT - YORKSHIRE This cold water storage tank wasn't leaking, but as you can see the internal surfaces 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. The internal surfaces were cleaned and keyed by sand blasting. We used recycled glass as our blast media. Once prepped we 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.
