Tendon Scan
Tendon Scan

TendonScan®  is a comprehensive post tension tendon inspection service that utilizes the latest in non destructive evaluation (NDE) and nondestructive testing (NDT) technologies to locate and assess both anomaly’s on the surface as well as section loss (loss of metallic area) and corrosion inside the steel strands of external tendons of segmental structures.

We have two separate patented portable units, one that utilizes RF an advancement in ECT Electrical Capacitance  Imaging  which  locates air, water and bleeding grout and another that utilizes Magnetic Flux Leakage to detect corrosion and locate section loss within a post tension tendon. At this time we have discontinued the ECT unit in favor of MFL. Recognizing that after locating air, water or bleeding grout asset owners would quickly ask if there were broken wires or deterioration, IPC felt that there was no need to utilize ECT as a preliminary inspection to MFL. 

A proprietary tendon condition assessment report is generated identifying locations and sizes of any discontinuities.

TendonScan® is IPC’s term for their light weight,  battery operated post tension tendon inspection system that couples and travels along a tendon performing a MRI like inspection of the material within the tendon. The inspector stands at the control station located on a wheeled cart and moves along with the sensor. The sensor uses wireless connectivity to transmit the MRI like data to the control station where the inspector performs real-time assessments of the discontinuities within the tendon.

TendonScan® utilizes proprietary patented leading edge non-destructive testing (NDT) technology. The nondestructive testing NDT method used is based on an advancement over the outdated Electrical Capacitance  (ECT).   Magnetic Flux Leakage is the industry’s newest NDT technologies that allows inspectors to perform MRI like inspections of the entire external bridge tendons.

The results provide a condition assessment of the internal sections of the tendon identifying the locations and sizes of section loss in the steel as well anomaly’s on the surface. Magnetic flux leakage locates section loss and corrosion and is becoming more popular as the universal technology needed to properly assess our ageing infrastructure. IPC’s robotic TendonScan unit is the first of its kind that integrates MFL (Magnetic Flux Leakage) specialized software and robotics to easily access and inspection post tension tendons.

The most advanced nondestructive evaluation “NDE” of external tendons within a segmental bridge structure can show where tendons need to be immediately repaired or replaced.

How Are Post Tension Tendon Inspections Conducted?

The average inspection team is composed of three personnel, the equipment weights lightweight, self propelled, operates on battery power with wireless connectivity to the control station.

The inspections are real-time with minimum back office processing. TendonScan® provides the quantitative data the department of transportation requires to properly allocate their asset to conduct repairs in order of importance. An advanced condition assessment report is provided to the asset owner.

Whether your project requires a baseline condition assessment, monitoring healthy tendons for preventative maintenance or locating corrosion, TendonScan® is the best method for inspecting post tension tendons known today.
