Since its beginnings in university research, FDH has maintained a strong focus on innovation and R&D. Our expertise is applied towards continued refinement, improvement, and validation of existing technology, as well as the development of new nondestructive methods to solve unique problems in civil infrastructure.
In 2009, the US Army Corps of Engineers (USACE) approached FDH with a request to develop a new NDT technique for pretensioned steel anchor rods in USACE dams. Working with USACE, FDH developed a fast, easy, and safe test method using dispersive wave analysis, which was successfully validated in field trials.
FDH has been awarded three U.S. patents:
- Mapping Method of Concrete Foundations (U.S. Patent 7548192)
- Determining Tension in a Rod (U.S. Patent 8096195)
- Method for Determining Tension in a Rod (U.S. Patent 8176800)
- Digital Signal Analysis
- NDT Computer Analysis Software Development
- NDT Methodology Development and Validation
- Structural Modeling, Testing and Validation
- Specialized Structural and Foundation Investigation
