"Being a Hurricane Shutter expert, I feel it is of the utmost importance to have structure scanned before penetrating. Although most condo specifications do not require this service to be done, for a modest fee Ground Penetrating Radar Systems, Inc., is always there for us with their special equipment to prepare a radar spec. in a punctual, professional manner."

"Dear Chris,

Uretek has been using GPRS services for many years. They are extremely reliable and accurate in their GPR surveys they perform for us. We use them approximately 10 to 12 times per week on our projects. Justin performs a large portion of our GPR needs on a daily basis. He is punctual and a very hard worker. He strives for excellence on every job. We use him to locate underground utilities, pool lines, post tension cables, etc."

Thank you,

Isaac Boyette

"I have had the pleasure to work with Justin and have found him to always be accommodating and consistently pleasant to work with. Besides always responding promptly to our GPR requests, Justin has managed to adjust his schedule to accommodate LRE’s short notice GPR requests also.

Justin always contacts me via email or a phone call should he be running slightly behind schedule or able to arrive at a job site ahead of schedule.

I look forward to working with Justin, as he is ambitious and is always willing to make the effort to do what it takes to accommodate his clients. Overall, I feel Justin represents GPRS with excellent professionalism."

"Mr. Yunker,

We recently had you provide us with your locating services at a local fuel terminal facility. We were in need of locating underground utilities and other obstructions to excavate for concrete foundations and underground conduit installations.

This was a very large and congested area to perform this task. I just wanted to take this opportunity to thank you for your services. Your mobilization response time was remarkable. It helped us greatly in meeting the demands of our client. The work itself was completed in less time than expected and with all the excavating we performed, we did not run into any unforeseen obstructions. Your EMR and TRIR safety records are outstanding, thus allowing us to use your services with safety conscious clients now and in the future.

Thank you for a job well done."

"Chris & Justin,

We wanted to take the time this morning to let you both know how impressed and pleased we at Sullivan-Tassin, Inc. were with your services. Our collective staff have been in the construction business for years and were pleasantly surprised at the level of professionalism that your company displayed. The degree of “mark out” really eliminated the “doubt” factor when dealing with PT construction.

Keep up the good work."
