Problem: The tank had developed a void between its annular ring and plinth substrate. The asset owner had concerns that if the void had been left to deteriorate, adverse weather conditions and moister/condensation would accumulate and track under the base of the tank. This would inevitably lead to corrosion of the tank base, leakage or even a tank failure.

Application Method

Once the substrate has been prepared to a standard of minimum surface profile of 75µm and a surface cleanliness of SA 2½, Belzona applicators rebuilt the damaged areas under the annular ring using Belzona 4131 to a 45° fillet which will encourage water flow away from the tank. Once complete the Belzona Tank Base Sealing system was applied in accordance with Know-How system leaflet GSS-03 using Belzona 3131 at a 500mm wide band around the complete circumference.
