Yes. After proper surface preparation, sealing systems can be applied to both new and in-service tanks, providing long-term protection even if some corrosion has already occurred.
An external sealing system creates a continuous, watertight barrier around the tank base, blocking water penetration and stopping crevice corrosion before it starts.
Once corrosion develops at the base, repairs are difficult, costly, and may require tank replacement or extended downtime. Preventing water ingress at the perimeter joint is more effective and cost-efficient than trying to remediate advanced corrosion damage.
Corrosion at tank bases often begins when moisture enters the gap between the tank chime and concrete foundation. This trapped water promotes crevice corrosion, which can spread under the tank bottom and compromise its integrity.
