TendonScan® Post Tension Tendon Inspection Service

Post Tension Tendon Inspection Video
Post tension tendon

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 section loss (loss of metallic area) and corrosion in external tendons of segmental structures.


Post Tension Tendon Field Video. Locating loss of metallic Area!

We have two separate patented portable units that utilizes RF an advancement in MFL 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 (Infrastructure Preservation Corporation) IPC’s term that encompasses their robotic inspection service for post tension tendons. TendonScan® is comprised of a lightweight,  battery operated service unit that couples onto the tendon 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 results are transmitted wirelessly to the inspection station.

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® units utilizes proprietary patented leading edge non-destructive testing (NDT) technology and comes in a 240 and 360 degree unit. For tendons that lay on the ground or are on the exterior of a wall the 240 degree unit is utilized. When the entire tendon is exposed the 360 degree unit can be utilized. Magnetic Flux Leakage  is the industry’s newest NDT technologies that allows our inspectors to perform MRI like inspections of external bridge tendons.

The magnetic flux unit locates section loss and corrosion and is currently the only inspection method that provides the amount of quantitative date to properly assess our ageing infrastructure.

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 two personnel, the equipment is 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.
