Problem: Over the years the bitumen and sand base under this 36m diameter tank had compressed, to such an extent that the annular rim was now at least 10mm below the surrounding concrete plinth. Water was actually being captured at the rim which had dramatically increased the risk of under base corrosion. Various mastics had been tried in the past, but all failed quickly.

Belzona Facts
For many years this customer had recognised the long-term benefits of using the Belzona Tank Base Sealing system. After reprofiling the plinth, the Belzona Tank Base Seal was installed around the full diameter, preventing any risk of water ingress to the base. The work was inspected again in 2017 and is still in perfect condition. To date this client has protected over 50 tanks with the Belzona Tank Base Seal solution.
