CIPP Example 1

---

Message: CIPP Increased 36-in diameter CMP Pipe Strength.

A 36-in CMP was rehabilitated using CIPP technology. After curing, the pipe demonstrated a significant increase in culvert pipe strength. The ultimate load bearing strength increased from 1,377 pound force foot (lbf/ft) to 3,095 lbf/ft, and the D-Load strength increased from 689 pound force per square foot (lbf/sq. ft) to 1,548 lbf/sq.ft.
