The method of Sonic Integrity Testing (SIT/PIT)
PIle Integrity Testing (PIT) or Low Strain Impact Testing (LSIT) has been developed as Sonic Integrity Testing SIT) in the Netherlands in the 1960s. It’s a fast and cost-effective testing method to determine defects in piles, to check the condition of deep foundation elements (as-built versus designed or desired). Major cracks, necking, and soil inclusions can be determined and indicate the pile length.
Allnamics' PDR is the wireless data acquisition unit for Static, Rapid and Dynamic Load Testing
Wireless monitoring avoids cable handling during onshore and offshore Dynamic Load Testing
Allnamics-SIT software gives a clear presentation of the measured signals, as well during testing as in an automated generated report
SIT-USB designed by the inventors
For low strain testing of concrete piles, to determine the integrity of piles, Allnamics engineers have developed their first SIT equipment back in the 1960s. Based on the gained experience, both in developing equipment and more in performing tests and interpretation of test results, Allnamics has developed the state-of-the-art Pile Integrity Testing monitoring system which can be used in combination with the PDR (SIT-PDR) and with any laptop computer, using the USB port (SIT-USB). With the advanced sensor, high-quality sonic measurements can be made.
The professional SIT system is fully capable of the testing of deep foundations and foundation piles to efficiently reveal potential defects and indicates pile length.
The powerful and easy-to-use software enables analysis of the results directly on site. Signals and results can be shared with colleagues and the office.
The testing engineer is supported by the voice response option of the SIT software.
The Site Characteristic Signal
To distinguish reflections caused by the soil from that of pile defects, signals of individual piles have to be compared to Site Characteristic Signal. The Site Characteristic Signal represents all soil influences. Piles that show signals deviating from the Site Characteristic Signal are suspected and need extra analysis or additional testing.
The Allnamics-SIT presents signals of all individual piles against the Site Characteristic Signal.

ALLWAVE-SIT for Quantitative Interpretation
In addition to the normal qualitative interpretation, AllWave-SIT is available for Signal Matching techniques to quantify detected defects. The results of the AllWave-SIT Signal Matching process are the dimensions of the pile.

Allnamics Training courses
Allnamics Academy offers training courses in low strain impact testing. Dedicated training courses for test engineers in how to obtain interpretable signals. And for consulting engineers in analyzing and interpreting signals, for clients and others who have to rely on pile tests in understanding the results and reports, including possibilities and limitations of pile integrity testing.
