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 voids, water, bleeding grout (grout not cured) as well as section loss (loss of metallic area) and corrosion in 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.

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

TendonScan® is IPC’s term that encompasses both of these services. The RF unit is a light weight, battery operated 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.

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 The nondestructive testing NDT method used is based on RF an advancement over the outdated Electrical Capacitance (ECT).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

The results provide a condition assessment of the internal sections of the tendon identifying the locations and sizes of water, air, and bleeding grout. The mag flux unit locates section loss and corrosion and is becoming more popular as the need to properly assess our ageing infrastructure becomes more critical.

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.
