GPR Distilled 21-05-21

“GPR was the topic of this webinar. It is an invaluable tool that the Testing Industry has at its disposal, however it cannot be used in all scenarios.

This webinar provides insights of the origins of GPR alongside its applications and covers the limitations of the technology

HTA believe it is vitally important to share knowledge that benefits our industry as we are in the business of saving lives not merely investigating structures.

Thank you all who attended and asked questions, we look forward to chatting with you on our next event.”

The Innovative Approach to PTSI

Thank you for watching.

Well we did it, our first Webinar seemed to go without a hitch.

❝ I would like to thank all of you who took time to watch our webinar and raised good questions in respect to the PTSI Approach which HTA undertake.

An additional thank you goes to my Associate Director Steve Neville, who carried out a great presentation today.
