Belzona Facts
The ability to grout the tank with proper materials put this tank back in service as it could not be used in this condition. This increased the storage capacity at this terminal considerably and restored this asset. Belzona 7211 and 5811 will not shrink and have high compressive loads preventing future failure and water ingress that causes freeze thaw problems.
