Waterproofing (ASTM C-642)
Absorption test procedures were conducted in accordance with ASTM C-642, using normal weight, non– air-entrained concrete, manufactured per ASTM C-672. Samples submerged in water.
Results: 0.33% absorption after 48 hours. 1.04% absorption after 50 days.

Eliminates Scaling (ASTM C 672)
Rated 0 (no scaling) after 100 freeze/thaw cycles on concrete treated with Cretedefender™.
Rated 5 (severe scaling) after 100 freeze/thaw cycles on untreated concrete.

Increases Abrasion resistance (ASTM C-779)
A rotating abrasive disk grinder was applied to both a treated and non-treated sample of concrete.
Test results: After 30 minutes of grinding, wear on the sample treated with CreteDefender was just 0.044 inches. Wear on the untreated sample was 0.080 inches.
CreteDefender increases abrasion resistance of concrete by 45%.

Inhibits chemical attack (see chart)
Exceeds OSHA standard for slip resistance on polished concrete floors.
Although OSHA does not have a mandate for a friction coefficient, they do indicate a reasonable slip resistant friction coefficient of 0.5 or more. In testing, polished concrete treated with CreteDefender had an average friction coefficient of 0.67, which exceeds the indicated value.

Increases slip resistance on broom finished concrete by over 6% (ASTM E-274)
The Ohio Department of Transportation conducted a slip resistance test in accordance with ASTM E-274 and concluded that the average increase in slip resistance on their test was 6.1%
