About NDT Corporation
NDT Corporation offers customers almost 30 years of expertise in assessing concrete infrastructure.
NDT History
NDT Corporation was founded in 1994 by Paul Fisk and Richard Holt. Paul and Dick were colleagues at Weston Geophysical for 20 years, where they developed expertise in seismic risk analysis for nuclear power plants. During that time, they discovered that the same testing protocol could be used to determine the condition and strength of concrete.
They started NDT Corporation with the mission to use proven geophysical survey methods to evaluate concrete structures and to provide those services to civil infrastructure owners and engineers. They quickly earned a reputation for delivering quality data with exceptional customer service.
Over NDT Corporation’s 30 years, the growth in the business lead led to the addition of several key staff along the way, who develop themselves professionally while also helping to take NDT to the next level. The key members were Keith Holster, Ben Armitage, and Tim Westerlind. Ben was hired in 1996, Keith in 1997, and Tim in 2005. These three individuals remain invaluable to today’s operation, bringing extensive knowledge and expertise acquired over 74 years. Ben, Keith, and Tim are experts in the field of NDT, with vast experience in data collection and analysis. Their combined knowledge and expertise in the non-destructive testing, set a benchmark for excellence that no other company can match. These critical members of NDT Corporation are proud to carry on the legacy of Paul and Dick and are instrumental in shaping our future.
Paul ultimately retired from NDT in 2021, and since 2017, Vice President Bill Horne has taken over leading NDT Corporation. Bill previously worked for CHA and regularly hired NDT Corporation to support CHA projects. As a result, Bill has a long history of knowing Paul, Ben, Keith, and Tim. Which made him an excellent choice to lead this highly experienced team when Paul stepped away.
Proprietary Equipment
Since their existence, NDT has been on the forefront of developing advanced non-destructive technology.
If a product doesn’t meet the highest standards for quality and efficiency, NDT will develop the tools internally. Over the years, they’ve refined their equipment to provide the most effective and efficient data collection and accuracy.
Their proprietary impact echo (IE) and pulse velocity (PV) system simultaneously collects IE/PV data to assess reinforced concrete for delamination, voids, cracking, and gives an in-situ compressive strength. Their IE/PV system can also be used to inspect post-tension (PT) grout voids. NDT has one of the most efficient and accurate systems to locate the presence of grout voids in PT ducts.
In addition, they worked with the Federal Railroad Administration to develop an automated railroad crosstie inspection tool, a non-destructive method to assess the internal condition of concrete crossties along railroads.
NDT Corporation continues to work on advance technology in the evaluation of reinforced concrete infrastructure.
Experience You Can Rely On
Since 1994, NDT has built a reputation for delivering reliable data, practical insight, and responsive service on technically complex projects. Our team combines decades of field experience with advanced testing technologies to produce results that are clear, defensible, and actionable for engineers and owners.
