Non-Destructive Testing
Insight for Infrastructure.
NDT Corporation provides non-destructive and geophysical testing services to evaluate the condition, integrity, and performance of concrete and subsurface infrastructure. Our testing delivers quantitative data that helps engineers and owners make informed decisions related to condition assessment, repair design, rehabilitation strategies, and asset management.
Our services provide the data engineers need to identify common structural issues, without damaging the structure.
