Share Manned Entry Electromagnetic Inspection Tools
Manned entry electromagnetic tools are ideal for evaluating the condition of prestressed concrete cyclider pipe (PCCP) water and wastewater mains that have been depressurized and either completely or partially dewatered.

Our experienced trained field technicians will travel inside the pipeline with the tools in order to identify distressed sections.
Once the pipe is dewatered, the equipment can be deployed to locate and estimate existing wire breaks along individual pipe sections. These tools generate an electromagnetic field inside the PCCP and measures the changes within this field caused by broken wires.
Field teams can inspect up to ten miles per day, and qualitative results can be presented. A comprehensive report is submitted within weeks which provides an estimated number of wire breaks and the location of wire breaks within each pipe section.
Advantages of Manned Entry Inspection
- Provides the most thorough and accurate PCCP assessment as data is viewed in real time and can be correlated to internal visual inspection results
- Re-inspection is relatively straightforward if a follow up is necessary
- Defects can be mapped above ground during or soon after survey
Internal Visual & Sounding for PCCP
During a manned electromagnetic inspection, field teams can also perform internal visual and sounding inspections through our engineering services division. This will test for any visible and audible signs of pipe damage such as pitting, cracking and delamination of the pipe wall.
With this information, pipeline owners can prioritize repair, replacement and monitoring programs.
