Concrete Alkalinity - ACTECH Video Interview at 2017 WOC
RISK Management TIP #3:
Check Your Product Data Sheets for alkalinity/pH tolerances.
- Concrete alkalinity ranges from pH 11.5 to 13.5.
- Most adhesives list pH 8 to 9 as their upper limit.
- Most epoxy-based protective coatings list an upper tolerance of pH 11 to 12.
An independently tested ASTM F3010-13 compliant above-slab liquid-applied membrane-forming resin barrier should take moisture and alkalinity totally out of your risk equation
