Understanding RCC Repairs: A Guide for Mumbai Buildings
Saving the Skeleton of Your Building
Reinforced Cement Concrete (RCC) is the backbone of Mumbai's high-rises. However, salt-laden air and monsoon seepage lead to 'spalling'—where rusted steel expands and cracks the concrete. In 2026, we use a systematic restoration process.
The Repair Protocol:
- Steel Descaling: Removing rust from exposed rebars until the shiny metal surface is reached.
- Zinc-Rich Priming: Applying a sacrificial coating to the steel to prevent future electrolytic corrosion.
- Polymer-Modified Mortar (PMM): Using high-strength, non-shrink mortar to rebuild the concrete section and restore structural integrity.
Frequently Asked Questions (FAQ)
Look for 'bulging' plaster, brown rust stains on ceilings, or chunks of concrete falling from balconies (spalling).
For 2026 safety standards, patch-work is temporary. A proper structural audit should determine if the repair needs to be localized or comprehensive.
