For over 25 years, NDT Corporation has provided nondestructive testing services for all types of materials including concrete, steel, masonry, timber, asphalt, soil, and rock. NDT has successfully completed over 1,000 projects for consulting engineers, public and private owners, contractors, and insurance companies.  As an industry leading testing company, NDT has developed proprietary testing equipment referred to as Sonic/ultrasonic testing.  This system uses a projectile impact energy source and a hand-held sensor array to record direct shear wave and compressional wave information. Energy wave velocities (Pulse Velocity ASTM C597-16) and resonant frequency measurements (Impact Echo ASTM C1383-15) are used to determine the condition (concrete compressive strength) and dimensions of various materials. 

Through many years of testing experience, NDT is proud of our reputation for innovation by developing and upgrading custom non-destructive testing equipment, sensors, and software. Signal conditioning, pre-amplification, filtering, analog/digital conversion, archiving, and field display for quality control is done on a portable computer.
