Roof Parking Waterproofing
Waterproofing a rooftop parking garage stops moisture and contaminates 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 a 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.
