Concrete Spalling and Balcony Slab Repair Design
Engineering for spalling concrete, exposed rebar and deteriorated balconies, slabs and columns, common in coastal and older buildings.
What the work involves
Spalling happens when reinforcing steel corrodes and expands, breaking off the concrete cover. Engineers survey the extent with sounding and testing, determine causes (chlorides, carbonation, water intrusion, inadequate cover), and prepare repair drawings specifying removal limits, rebar treatment or replacement, repair materials and protective coatings. Proper design matters because patching over active corrosion often fails within a few years.
Local conditions we plan for
- Coastal flooding and storm surge in New York City and Long Island
- Frost depth and heavy snow upstate
- Aging infrastructure, bridges and older buildings
- Lake effect snow loads in western New York
Building code: 2024 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).
When you need it
- Chunks of concrete falling from balconies, soffits or columns
- Rust stains or exposed reinforcing steel
- Condo milestone or facade report calls for repairs
