Sonic/Ultrasonic Testing

Precision Foundation and Structural Integrity Testing

Non-Destructive Foundation Length and Condition Assessment

Ultrasonic Methods combine Impact-Echo (IE) Sonic Echo (SE), and Impulse Response (IR) technology to provide a comprehensive concrete integrity assessment. These low strain integrity tests involve impacting the exposed end of a structural element and measuring the travel time of the sonic wave after it returns from reflecting from an anomaly or the other (buried) end.

The tests are conducted  according to ASTM C1383 or ASTM C1740 using specialized equipment that generates controlled wave energy to measure concrete element thickness and estimated compressive strength; detect structural anomalies including delaminations and unconsolidated material; and locate underlying voids. By analyzing both time domain and frequency domain responses, these complementary methods provide reliable condition assessment eliminating the requirement for destructive and costly excavation or drilling.

Capabilities

Dual-Domain Analysis
SE analyzes reflections in the time domain while IR converts data to the frequency domain, providing comprehensive wave analysis.
Precise Depth Measurement
Concrete thickness calculated using wave velocity and reflection time with equation D = V*(t/2) for accurate results.
Low Strain Testing
Non-destructive impact testing preserves structural integrity while providing detailed concrete condition data.

Applications

Ultrasonic Methods are essential for various assessment projects:

  • Concrete thickness measurements
  • Concrete integrity evaluation
  • Bridge load ratings
  • Quality assurance on new construction
