Cameron Manners of IPT talks about their Pull-in-Place, or CIPP, designed for under slab pipe lining. They take a CIPP liner tube manufactured in their Abilene, Texas, plant, and introduce an epoxy to it. So basically going to do a two-part epoxy into their felt tube. Kits come 150 feet long, so you can measure off whatever liner size you have, and pre-cut it. The great thing about this system is that two points of access are needed. But those two points of access already exist–a roof vent, a toilet stub, or a clean out. Zero digging is required. Once the epoxy is in there, you pull the system into place, inflate it, and cure it. You can do ambient cure, steam cure, or hot water cure. Hot water and steam cure take less than one hour for a length of pipe. Ambient cures run anywhere from two hours up to six hours. works on 2 inch and 3 inch lines. All epoxies 100 zero VOCs, with 2:1 mix ratios. The easiest system out there by far.
