Below is an example of actual preservation saving:

Single application of GSB-88

GSB-88 increased useful life 29%

Savings = $0.11 per sq/yd per year

1M sq/yds save $110K per year

12 years save $1.32M per 1M sq/yds

2 applications = save $.18 per sq/yd

15 years save $2.7M per 1M sq/yd

More than 3M sq/yds treated at PDX with GSB-88 including main runways
