Nondestructive Evaluation

Nondestructive Evaluation (NDE) and Nondestructive Testing (NDT) are non-invasive methods used to evaluate the extent of damage or defects in engineered structures.  These techniques often provide information about conditions not observable using visual inspection alone.

Investigation

A comprehensive investigation of structural problems is often achieved through a careful mix of visual inspection, NDE/NDT, laboratory testing, and minimally intrusive material sampling. Properly managed, this approach is often more cost effective and informative than a more traditional investigation. Some of the most common applications include:

 Floor Slabs & Pavements

  • Locating dowel bars, subsurface voids and internal delamination
  • Identifying defects such as voids, low thickness and poor subgrade

Concrete Structures

  • Locating embedded steel and assessing corrosion
  • Identifying cold joints, poor consolidation, and areas of deterioration

Masonry Structures

  • Evaluating presence of reinforcing bars and grout in CMU walls
