Roof Parking Waterproofing
Waterproofing a rooftop parking garage stops moisture and contaminants from reaching the depths of reinforcing steel to allow corrosion cell formation. A new structure maintains high pH levels surrounding embedded steel keeping the “Passivating Layer” on steel intact, preventing rusting of post-tensioned tendons as well as rebar. The “Dry” concrete interior provides a high ohms resistance to concrete but is below the thresholds required of an Impressed Cathodic System installation. Keeping a low moisture environment prevents variances in resistance creating “Hot Spots” and premature consumption of anodes, Associated with these systems. A high Ohms resistance concrete offers protection to prevent secondary spalling and “Anodic Ring Effect” on parking deck repair sites.
