Profile and Testimonials

Company Profile

IRISNDT is a successful blend of forward-looking NDT and engineering companies providing a broad range of inspection, testing, engineering, heat treatment, and software services to the process industries. The company is run both by the founders of the original, individual companies and technical managers active in the field.

Our managers work directly with our customers and keep abreast of developing technology. This is fundamental to our reputation for quality, customer service, and an outstanding safety record. We also look after our employees. Our business is built on credibility and reputation, only achievable by retaining long-term employees. In a very real sense, our product is our people. Taking care of our people and their families is what we do because we depend on each other to do our jobs well and safely.

Established in Edmonton, Canada in 1953, IRISNDT has provided quality NDT services for over 65 years. Operations in the USA, the UK, and Australia have been added over the past 25 years.

UK operations started in 2006 with the Stockton-on-Tees based specialist NDT services branch, Matrix Inspection. This new company provided automated UT testing, guided wave ultrasonics, and acoustic emission testing services. Adding the broader range and depth of NDT and laboratory services of Immingham based SPI-NDT in 2010 greatly improved the depth and scope of our services.

Like IRISNDT, SPI started out with radiographic testing in 1987 and developed into a broadly based NDT services company. This included achievement of ISO-9001 certification for its NDT and mechanical testing services. By 2007, SPI was a medium to large third-party inspection company carrying out major projects for leading UK main contractors and end users. A new purpose-built facility in Immingham boasted three radiography bays, a new larger electro-furnace and mechanical testing laboratory. These were served by a five tonne overhead crane and generous yard space for transport and handling of larger assemblies.

By this time the company had also branched out into ship surveys with the acquisition of Ultrarad Technical Services Hull Ltd holding certificates from ABS, BV, DNV, GL, NK Lloyds, and RINA. This operation now includes storage tank and pipeline inspection under the EEMUA and API standards.

The 2010 merger with IRISNDT included the heat treatment services of Thermal Technologies. This new company, SPI-Matrix, boasted a range of NDT services that few could rival backed by the considerable resources of the Canadian parent company.

The much larger operation, now including rope access services, combined with customer demand meant further upgrading of the quality management system to meet the BS EN ISO/IEC 17020 standard.

Incorporation of Thermal Technologies Inc. allowed creation of a broader range of heat treatment services. This included expansion of the existing workshop heat treatment ovens and addition site heat treatment and bolting services. These services achieved accreditation certification to BS EN ISO 9001 within six months of their inception.

Further growth was achieved by acquisition of the NDT and Heat Treatment business of Assured Inspection Services in 2011. This added the bases in Chatham and Pembroke Dock to the existing Stockton-on-Tees, Hull, and Immingham locations as well as Assured’s expertise and experience in the power industry.

September 2014 saw the opening of a new, much larger main office and test facilities in Immingham, and adoption of the parent company name: IRISNDT Limited. The 36,000 ft2 [3345m2] building complex houses X-radiography bays, heat treatment ovens, machine shop and mechanical testing laboratory. The largest radiography bay is 14m long. This complemented by a 10 tonne crane (to be upgraded to 20) and 14m heat treatment oven makes it the largest facility of its kind in the region.

In May 2015, IRISNDT acquired the NDT and Heat Treatment business of QA NDE. This Ellesmere Port branch office gave the company its 6th operating location.

In 2019, IRISNDT opened its facility in Derby.

In early 2022, IRISNDT acquired James Fisher NDT of Deeside.  The Ellesmere Port office was consolidated with the new Deeside operations.

Beyond the new facilities, IRISNDT continues development of both the existing NDT and specialist services. This includes training and development of personnel, adding state of the art equipment and new technologies such as 3D Laser Scanning, Digital Radiography, high temperature guided wave testing, and optical emission spectrometry for materials analysis.

Refinery shutdown work:

“We set out to be safe, on time and on budget and hit all those goals. We proved again that if we stay safe as our No.1 priority then the rest usually takes care of itself. The overall duration was looking like 49 days with the refractory scope addition we planned for and the extra 4 days for weekends off but had we started warming up today then we would have been looking at a 44 day stream to stream event.

Thanks again for your commitment to safety and dedication to quality work. No different to how you normally perform but the sheer scale of activity always makes shutdowns that bit more of a challenge for everyone.”

“In light of Chris’s excellent work during this shutdown….and more importantly his excellent find on the Dxxxx crack which we could very easily and almost did miss……is there any chance of a spot recognition for him?”


Site inspection:

“Thanks for the NDT support work last week which was all completed to a high standard in a timely and safe manner by Phil, Karl & Rob and I look forward to receiving the final reports. It would be a great help if you could email PDF copies and send the hard copies for my attention at the Stockton address below.”



“Just a note to say I’ve had a read through your reports on the 3 tanks inspected here at Medway, and they are excellent. They’re really well laid out and supplied us with all the information required.

Thanks for all your efforts”


Laser scanning:

“Wow, very impressed. You want to get your head around this Tom, make sure you understand every detail about the report.

Well done Martin, this technology is phenomenal.”


Call out:

“Please find attached the final request for this mornings impromptu MPI.

Thanks for doing us proud as usual :)”

Rope Access:

“I was wondering if it would be possible to give some recognition to three IRSINDT rope access guys. I have been working down at Dock Silos for the past couple of days doing some assisted abseiling to look at the skip hoist steelwork and rails. This was a high risk job and required a lot of safety measures to be put in place. The three guys I worked with did an exeptional job in making me feel and keeping me safe at all times. They were very patient with me as well as I had never done an assisted abseil before!!”
