FIRE WATER TANK REFURBISHMENT - YORKSHIRE This vertical cylindrical cold water storage tank wasn't leaking, but as you can see the internal surfaces needed refurbishment to reinstate the tanks integrity. The tank stood at over 8m high so we got confined space trained scaffolders in to erect safe working platforms around the internal perimeter. The 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 blasting media. When the surfaces prepared we applied our fibreglass lining system to the complete wall area, sealing onto the concrete floor . This system offered our client a maintenance free finish that will last for at least the next 20 years.
