Low Strain Impact Integrity Testing is a non-destructive method for assessing the integrity of augered cast-in-place piles, drilled shafts, or driven concrete or timber piles. If significant defects are present, test results can estimate their size and location, as well as determine pile length.
The Low Strain Test, also known as Pile Integrity Test (PIT) are typically conducted post-installation and curing of the foundation, requiring minimal pile preparation. Due to their simplicity, speed, and cost-effectiveness, these integrity tests can be applied to 100% of piles on-site, and can sometimes be used for existing foundations.
YJACK engineers use a handheld hammer to strike the top of the foundation. The impact generates a compressive stress wave within the pile or shaft, monitored by an accelerometer placed atop the structure. As this stress wave travels down the shaft, it reflects upon encountering the base or irregularities, altering the acceleration signal at the pile top. This signal is captured and analyzed using Pile Integrity Tester (PIT) equipment, interpreted by experienced YJACK engineers.
Pile Integrity Testing has been widely adopted globally for many years and conforms to the ASTM D5882 standard, which outlines the procedures for Low Strain Impact Integrity Testing of Deep Foundations.
Our LSPIT test employs MrGeo - Low Strain Pile Integrity Tester, an advanced technology providing substantial benefits to stakeholders in the pile testing industry.
The Low Strain Pile Integrity Tester (LSPIT) is a state-of-the-art testing equipment to perform low strain pile integrity test (LS) on deep foundation piles. The basic system is to test the pile with exposed pile head and available to attach gauges to measure velocity signal.
