Abstract
The article presents the existing methods of uniformity test of concrete bored piles. These methods include: testing of drilled cores, seismic tests, radioisotope or ultrasonic testing. The best method of these is the end-to-end testing with ultrasound. In this technique, there are no requirements for the rejection of the design. The article presents the accumulated results of tests of bored piles for continuity. Requirements of rejection for testing of bored piles are established. For the rejection of structures, we recommend using are coefficient of variation and the value of the relative deviation of the ultrasound velocity from the mean value.
