Problem: Our client's containment was facing corrosion from sulfuric acid and needed a new coating to protect the concrete secondary containment. The existing coating was buckling and there were hollow pockets underneath.

Before. Existing coating appeared not terrible but could easily be chipped away to reveal hollow concrete underneath.

Belzona 4111 was used to build a cove around the containment and pedestals on which the tank sits. We also used on heavily damaged areas.

Belzona 5811 was selected as the primer coat.

2 coats of Belzona 4311 to finish.
