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.
1. Initial condition of tank.
2. Annular rim creating channel for water.
3. Tank Base Seal application in 2010.
4. Tank revisited in 2017
