Fiberglass-reinforced felt liner from CIPP Corp. is a specially designed resin system developed to prevent premature hardening, and works well in the presence of water. These liners are designed with a 2-1 pressure safety factor through the ASTM F1216 design formula. They are a stand-alone pipe, needing no support of the host pipe to maintain their structural stability. They are ANSI/NSF 61, BNQ certified with safe drinking water in mind. Flow capacity is maintained, while corrosion becomes a problem of the past. Sizes from 6 inches on up are available, with installation typically taking only a few hours. Installation has minimal impact on the neighborhood and reinstatement is completely trenchless. 888/485-2477;
