Syrup Tank Base Corrosion Seal
Corroding syrup tank chime rebuilt and the base-to-foundation joint sealed to keep moisture from working back under the floor.
The challenge
A syrup storage tank corrodes at the chime, the lip where the shell meets the floor and sits down on the foundation. Moisture and spilled product collect in that joint and get trapped against the steel, so corrosion works in from the outside and underneath where it cannot be seen. The shell-to-floor steel wastes and thins, and the gap at the base lets more water back in to feed the attack. Left alone, the wasted chime threatens the integrity of the floor and risks a release of stored product onto the slab.
Our approach
We clean the chime and the base joint back to sound, profiled steel so the repair has something to grip. We rebuild the wasted and thinned steel at the shell-to-floor area with a cold-applied composite, restoring the lost profile with no hot work near the stored product. Then we form a sealing fillet along the base-to-foundation joint and coat the chime so water can no longer collect in the gap and sit against the steel. The whole job is cold-applied, which keeps the crew clear of welding around a tank holding product.
- Assess and mapWe inspect the chime and base joint to find the wasted steel, the trapped moisture, and how far the corrosion has worked under the floor edge.
- Surface prepWe clean the chime and the base-to-foundation joint back to sound, profiled steel so both the rebuild and the seal bond to clean metal.
- Rebuild wasted steelWe rebuild the thinned shell-to-floor steel with a cold-applied composite to restore the lost profile, with no hot work near the stored product.
- Seal the base jointWe form a sealing fillet along the base-to-foundation joint and coat the chime so water can no longer collect and sit against the steel.
- Inspect and return to serviceWe confirm the rebuild and the seal are sound, then hand the tank back ready to hold product.
The result
- Wasted chime steel rebuilt in place without cutting out plate or hot work
- Base-to-foundation joint sealed so moisture can no longer collect against the steel
- Under-base corrosion path closed off to slow further metal loss
- Work delivered by factory-trained and factory-certified Belzona applicators
