Oil Tank Repair - Middlesborough These light oil storage tanks in Teesside were corroding badly around the annular ring/ external apron. They needed immediate attention to protect them against further corrosion and the possibility of the tank leaking oil into the bund. The steel wall of the tanks and concrete aprons were sandblasted to key to take the fibreglass application. We applied our reconstructive fibreglass lining system up the tank wall and across the concrete plinth to ensure complete rainwater run off. This long term solution was applied to both tanks in this oil storage bund in Middlesborough.
