NDT Inspection of Prestressing Tendon Systems in Pressurized Concrete Containments

I am looking for an inspection process to determine cracking, corrosion, etc., of grouted prestressed tendons. The tendons consist of 19 x 0.62 inch diameter strands with access to the ends only.

Thank you

Re: NDT Inspection of Prestressing Tendon Systems in Pressurized Concrete Containments
In the UK a 7.5m long 6mm dia videoscope is used for looking at the tendons of prestressed bridge supports in preperation for increasing the weight limit.

Tendons were failing through corrosion as incorrect grouting procedures were leaving the tendons exposed.

Everest VIT has a video probe that would suit this application.
