Loading-Rack and Bund Concrete Rebuild
Spalled loading-rack deck and bund rebuilt and lined chemical-resistant so containment holds a spill instead of soaking into the slab.
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
The concrete under a product loading rack takes a constant beating from spills, drips, and weather, and the surrounding bund is meant to catch and hold any release. Over time the deck and the bund walls spalled and cracked, and the product worked its way down into the open concrete. Once the slab is cracked and porous, the containment can no longer be trusted to hold a release, because anything that lands there soaks into the concrete and finds its way out instead of staying in the bund. Left that way, a routine spill becomes an environmental problem and the loading area is out of compliance.
The Belzona approach
Work starts with chipping out the unsound, spalled concrete on the deck and the bund walls back to a solid base. A repair mortar then rebuilds the lost sections, and the surface is reprofiled so it drains the way it should instead of pooling product. Once the substrate is sound and shaped, the deck and the bund are lined with a chemical-resistant coating keyed to the product being loaded, sealing the cracks and tying the deck and walls together under one continuous barrier. The result is a loading area where a spill stays on the surface and inside the bund, where the crew can clean it up, instead of disappearing into the slab.
- Assess and confirm productThe loading rack and bund are walked to map the spalling, cracking, and porous areas, and the product being loaded is confirmed so the lining is keyed correctly.
- Chip out and prepThe unsound concrete is broken out back to a solid base and the deck and bund-wall surfaces prepared so the mortar and lining bond.
- Rebuild and reprofileA repair mortar rebuilds the spalled deck and bund walls, and the surface is reprofiled so it drains rather than pools.
- Seal and lineThe cracks are sealed and the deck and bund lined with a chemical-resistant coating as one continuous barrier over the rebuilt concrete.
- Return to serviceThe lined deck and bund are confirmed sound and the loading area handed back ready to hold a spill instead of letting it soak in.
The result
- Spalled deck and bund walls rebuilt to profile without tearing out and repouring the slab
- Cracks sealed and the surface reprofiled to drain instead of pooling product
- Deck and bund lined chemical-resistant as one continuous barrier keyed to the loaded product
- Containment that holds a release on the surface, delivered by factory-trained and factory-certified Belzona applicators
