Parallel Seismic available. Send inquiries to sales pile. The Pile Integrity Tester PIT gives peace of mind that a pile or shaft is free of major cracks and voids, prior to construction of the superstructure. It may be used on most concrete or wood foundations. The PIT may also be used to test piles integral in the structure, such as those supporting existing bridges or towers, and may assess their length. With the PIT, any form of the test is performed fast, potentially making it possible to test every pile on a job site.

Historical Version s - view previous versions of standard. More D The method works best on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles. These data assist evaluation of the pile cross-sectional area and length, the pile integrity and continuity, as well as consistency of the pile material, although evaluation is approximate. This test method will not provide information regarding the pile bearing capacity.
It is generally helpful to consider the soil profile, construction method and site records when evaluating data obtained by this method. Other useful information to consider and compare with results of this test includes low strain integrity test results of similar piles at the same site, concrete cylinder or core strength test results, automated monitoring data on equipment placing the concrete when augered piles are used, or information obtained from crosshole sonic logging Test Method D or thermal integrity profiling Test Methods D if available.
The time domain record is then evaluated for pile integrity. The data are evaluated usually in the frequency domain. This test method is applicable to long structural elements that function in a manner similar to any deep foundation units such as driven piles, augeured piles, or drilled shafts , regardless of their method of installation provided that they are receptive to low strain impact testing.

No other units of measurement are included in this standard. How one applies the results obtained using this standard is beyond its scope.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
