Downtown Slab Conditions and Repair Patterns

Downtown Cincinnati slabs reflect the building's use history. A residential loft conversion may have a slab that was originally a manufacturing or warehouse floor, with the surface contamination and modifications from those earlier uses. A 1970s parking structure has concrete that has been through 50 winters of freeze-thaw and salt exposure on open deck levels. A 19th century commercial building may have original slabs that have never had structural protection.

Each requires a different repair approach. Diamond grinding matched to the contamination history exposes sound concrete. Structural epoxy injection bonds hairline cracks. Polyurea fill addresses wider cracks with seasonal movement. Spalled and pitted areas are profiled back to sound concrete and rebuilt with structural patching compound.

Vapor Emission in Downtown Below-Grade Slabs

Below-grade and street-level slabs in the river-flat downtown environment have elevated vapor emission risk because of the higher humidity in the Ohio River valley basin. Every Downtown assessment includes vapor emission evaluation, particularly for below-grade spaces. Where elevated vapor is identified, specification accounts for it with appropriate primer chemistry.
