Bar-wrapped concrete cylinder pipe (AWWA C303 standard) is a composite pipe consisting of a steel cylinder helically wrapped with a mild steel rod and lined and coated with dense cement mortar. Using our Remote Field Testing (RFT) technology and complementary tools such as CCTV and LiDAR, PICA can detect the following:
- Cylinder corrosion
- Corroded/broken reinforcing bars
- Out-of-round and denting
- Liner spalling
Non-metallic pipe, such as HDPE, PVC, and FRP are subject to crushing (from overburden pressure) and point loads from rocks in trench backfill and often fail due to slow crack growth. HDPE can also fail due to weld problems. While they do not corrode, these pipes can still fail catastrophically or develop leaks. PICA’s CCTV and laser in-line inspection tools can find and quantify defects in non-metallic pipes. With access through manholes and clean-outs or ARVs, PICA’s high-resolution solutions can size defects with a high degree of precision.
