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
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (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
- Coastal building exposed to salt air
Frequently asked questions
How much does concrete Spalling and Balcony Slab Repair Design cost?
Across the US, concrete Spalling and Balcony Slab Repair Design usually costs $2,000 to $40,000. Estimate. Single-home repairs are at the low end; multi-story balcony programs are higher. Repair construction is separate.
How long does concrete Spalling and Balcony Slab Repair Design take?
Plan on 2 to 8 weeks for survey and design from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Do I need a licensed PE for concrete Spalling and Balcony Slab Repair Design?
In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
