Home > Services > Cross Hole SonicThis test is used for checking the homogeneity and integrity of concrete in deep foundation such as bored piles, drilled shafts, concrete piles or auger cast piles. In this test method, all the above will be designated “deep foundation elements.” The test measures the propagation time and relative energy of an ultrasonic pulse between parallel access ducts (cross hole) or in a single tube (single hole) installed in the deep foundation element. This method is Standardized by ASTM D6760 and most applicable when performed in tubes that are installed during construction.
