Theodore Roosevelt aptly said, “When you are asked if you can do a job, tell 'em, 'Certainly I can!'

There are four key elements to having a really good Cured-in-Place Pipe (CIPP) installation:
1. Proper saturation of the tube;
2. Proper inflation of the resin saturated tube in the host pipe;
3. A full and thorough curing of the resin system used; and
4. A proper cool-down of the CIPP.
