Response from the owner: Thank you Cam! We love working with Sway Mechanika!
Tony is very knowledgeable and highly skilled in what he does. He doesn't just scans your site and leaves. He explains in high detail as to what he seeing. Rainier GPR is the only company I trust doing my scans for my projects.
As a General Contractor with a thousand balls in the air at any one given time, I love working with Tony and his team. Rainier GPR is always quick to turn around pricing and scheduling short notice scans when necessary to keep our projects rolling.
The absolute best scanning company around! Tony is highly knowledgeable and goes above and beyond to communicate and explain things! RainierGPS has helped me out more than once when I was in a pinch! They are incredibly responsive! highly recommended!
We have been using Rainer GPR Concrete Scanning over the last year on many of our commercial building projects. Tony is reliable, good at what he does and documents his work very well. We work in a very fast pace/demanding market to help meet our clients building goals - I’ve made many last minute calls to Rainer GPR to scan a location and they find a way to make it work. Most importantly in my opinion is that their layout to document the scanned area is very clean and easy to read.
Rainier GPR came out and located some mystery runs of pipes and buried wires under a slab. (An old DIY radiant heat floor)They were extremely easy to work with, and relatively cheap considering what it saved us in the long run. THANKS!!
Tony was on time and extremely helpful in understanding how we needed to proceed in locating our utilities. Thanks Tony!
Fast response time, very friendly. Tony is very knowledgeable and informative. No wasted time, Tony gets right after it! Cheaper because he is faster.
RainierGPR is a high quality and professional organization. We did business with them for a concrete scanning project in conjunction with the installation of two commercial garage doors. Tony showed up on time and worked quickly to scan and mark the needed areas. We will be working with Tony and his team again in the future!
I am a commercial supervisor with 20 years experience and have worked with Tony in this capacity many times. Always, and I mean always a professional and level headed view towards his work and what his capacity is. You get complacent with work but one thing that always gets my skin to crawl is coring slabs! Integrity and trust is what helps set your mind at ease and this guy does it in spades. Have and always will use Tony for my scanning needs.
They were great! On time, kind, detailed, affordable. I had a very good experience.
Tony was great to work with, he is very knowledgeable in GPR. Tony explained to me what the equipment displayed and then transferred all that info onto the concrete floor. This gave me confidence that no pipes/conduits would be hit or damaged when cutting the concrete. Always scan your concrete before cutting! 1oz of prevention is worth it!!!!!
Would give 10 stars if I could! We had Tony scan a project with an unknown amount of utilities under the slab, he is very professional, did an extremely thorough job, and to top it off he is just a great guy to work with! We can now cut the concrete safely and with confidence. Rainier GPR is the only scanning company I would recommend.
Tony at Rainier GPR Concrete Scanning is an absolute pleasure to work with not only is Tony an expert in his field, but he's also an amazing instructor. He took the time to thoroughly explain the process and techniques of concrete scanning, making it easy for me to understand and follow along to make me a better scanner!

X-Ray Imaging vs. GPR: Comparative Advantages

When it comes to concrete scanning, both x-ray and GPR technologies offer unique advantages. X-ray imaging provides high-resolution images that clearly reveal the density and composition of various materials within concrete. This is particularly useful for detailed analysis. However, x-ray systems often require more setup time and can pose safety risks due to radiation exposure. In comparison, GPR from RainierGPR Concrete Scanning is a non-invasive method that uses radio waves to penetrate concrete, making it a safer option for both operators and surrounding personnel. GPR is also quicker to deploy and can cover larger areas in less time, enhancing its overall efficiency. While x-ray imaging is superior for precise details, GPR is better suited for broader inspections and immediate results. Each method has its place, but when considering safety, speed, and ease of use, GPR proves to be the more versatile tool for many concrete scanning needs. With the expertise of RainierGPR Concrete Scanning, you can trust that you’ll receive top-notch structural imaging and utility locating using the best technology available.
