Traditionally, static loading is the most common way of testing pile foundations. There are several accepted procedures to set-up and perform a static loading test, which are explained in detail in ASTM Standard D1143. In brief, static testing consists of gradually loading piles to failure, or to a required capacity level, while measuring the displacement of the pile head in order to assess the available resistance.  Some test piles are equipped with additional instrumentation (strain gages along the shaft, telltales, …) to determine the distribution of the available pile resistance.

Our team of engineers have developed automated testing systems and data acquisition software to eliminate human errors, and increase the sampling frequency and measurement accuracy for load testing.

Key Benefits of ASI's automated testing system

  • Easy to setup and use
  • Extremely accurate
  • Capable of collecting data at two-second intervals
  • All readings of load and displacement are taken simultaneously
  • Eliminates human errors in reading instruments
