Storage Tank Floor Reclamation
Corroded aboveground tank floor rebuilt and lined back to immersion service without cutting out plate.
A job completed with Belzona. This describes what the Belzona system does and how it goes on, not a record of a specific project by this distributor.
The challenge
An aboveground storage tank floor corrodes from both the underside and the topside. Pitting and metal loss spread across the plates and the weld seams, thinning the steel that holds the stored product. Left untreated, the floor risks a release and forces the tank out of service. The owner needed the floor back in service without cutting out and replacing plate, and without losing the turnaround window.
The Belzona approach
Work starts with grit-blasting the floor to clean, profiled steel so the repair bonds. A cold-applied composite rebuilds the pitted and thinned areas and the weld seams, restoring profile to the plates. Then a full-floor immersion-grade lining keyed to the stored product goes on, sealing the steel and the rebuilt areas under one continuous barrier. The floor is worked in stages, keeping the application productive on the turnaround clock.
- Assess and mapThe floor is inspected to locate pitting, metal loss, and seam damage, and the stored product is confirmed so the lining is keyed correctly.
- Grit-blast prepThe full floor is grit-blasted to a clean, profiled surface so both the composite and the lining bond to bare steel.
- Rebuild pitting and seamsA cold-applied composite rebuilds pitted areas, thinned plate, and weld seams, with no hot work and no plate replacement.
- Apply immersion liningA full-floor immersion-grade lining goes over the steel and rebuilt areas as one continuous barrier.
- Inspect and return to serviceThe lining is checked and the floor goes back to the owner within the turnaround window.
The result
- Floor returned to service without cutting out or replacing plate
- Pitting, metal loss, and weld seams rebuilt in place with no hot work
- Full-floor immersion lining keyed to the stored product, applied as one continuous barrier
- Work completed on the turnaround clock by factory-trained and factory-certified Belzona applicators
