NDT Corporation provides high-resolution nondestructive and geophysical testing services to assess concrete structures and foundation conditions. Our nondestructive testing (NDT) techniques provide a cost effective means to evaluate and document the internal condition of concrete. The results of our NDT testing are used to identify and map areas of weak, cracked, voided, delaminated concrete and determine its in-situ strength and dimensions (thickness, depth, length, etc). High-resolution geophysical testing techniques are used for the assessment of soil and bedrock foundations conditions.

Nondestructive Concrete Testing Services

Our sonic/ultrasonic nondestructive testing methods provide a documented, cost effective means of assessing the integrity, locating flaws, and determining as built characteristics of concrete structures and elements. Radar measurements are used to locate reinforcing and moisture laden cracks.

Geophysical Soil & Bedrock Testing Services

Geophysical testing methods provide an efficient means of assessing soil and bedrock conditions over large areas. These methods are very effective for minimizing an engineers risk by providing continuous data between borings.

Experience

Experience is the key to our success. NDT's founders Paul Fisk and Richard Holt have a combined 85 years of engineering geophysical and nondestructive testing experience.

Our field crews are experienced as well, with our senior field technicians having over 10 years of field testing experience.
