|Due to various design issues and operating conditions, the external base area of steel storage tanks is vulnerable to corrosion problems. This is due to thermal and/or physical movement of the tank which causes cracking and is compounded by precipitation that runs down the side of the tank, collecting and laying in the same area. Water contaminants then enter any
cracks between the concrete and steel, causing a steady deterioration of both materials.
The system seals the vulnerable area with a flexible but tough outer-armouring which is also highly weather resistant.
