SKAPS GT-131 is a needle-punched nonwoven geotextile made of 100% virgin polypropylene staple fibers, which are formed into a random network for dimensional stability. SKAPS GT-131 resists ultraviolet deterioration, rotting, biological degradation, and naturally encountered alkalis and acids. Polypropylene is stable within the pH range of 2 to 13. SKAPS GT-131 is NTPEP certified and meets requirements as per AASHTO Standards and/or D.O.T. Standards.
SKAPS GT-131 conforms to the Minimum Average Roll Values
