Problem: The tank and concrete saddles were showing some minor signs of corrosion at the joints. This was caused by standing water in these areas. The damage to the tank coating and concrete were only minimal, however if they were not repaired, the damage would have continued to deteriorate causing potential failure of the tank or the supports in the future.

Application Method
The failed concrete on the tank support was removed using hand tools. The repair area was then prepared to remove any remaining loose particles and dirt from the concrete areas. The concrete was then conditioned and rebuilt to match the surrounding concrete supports using Belzona 4131. Surface preparation of a 100mm band on the concrete and the tank was then undertaken, again using hand tools to remove any failing coating and rust. A two coat, reinforced system of Belzona 3131 was then used to create a seal between the tank and the concrete. A band of 200mm around the tank was applied to concrete interfaces.
