Pile Integrity Test

Pile Integrity Test in Kenya, Uganda, Tanzania, Rwanda, Somalia, Sudan, DRC Congo, Mozambique, Zambia, and the rest of the East African region.

A Pile Integrity Test (PIT) is a non-destructive test used to assess the integrity of deep foundation piles, such as driven piles, cast-in-place piles, or drilled shafts. The test is used to determine if a pile is damaged, defective, or has any voids or cracks that could affect its load-bearing capacity.

The test works by measuring the velocity of a stress wave that is generated at the top of the pile and travels down its length. An accelerometer is placed on the top of the pile to measure the wave's travel time and amplitude. The data is then analyzed to determine the pile's continuity, cross-sectional area, and the presence of any voids, cracks, or other defects.

There are several types of PIT tests, including the low-strain integrity test and the cross-hole sonic logging test. The low-strain test is typically used for piles that are driven or cast-in-place, while the cross-hole sonic logging test is used for drilled shafts.

PIT is a widely used and accepted method of assessing the integrity of deep foundation piles. It is an essential tool for ensuring that the piles meet the required specifications and are capable of supporting the intended load.

Our services include:

  1. Conducting PIT tests on deep foundation piles to evaluate their integrity, continuity, and potential defects.
  2. Using certified equipment and software to perform the PIT test, ensuring accurate and reliable results.
  3. Interpreting the PIT test results to determine if the pile is structurally sound or if there are any issues that need to be addressed.
  4. Providing a detailed report that includes the test results, an analysis of the findings, and any recommended corrective actions.
  5. Providing consultation and recommendations on pile installation, design, and construction based on the results of the PIT test.
  6. Conducting quality assurance testing during pile construction to ensure that the piles meet the required specifications.
  7. Offering follow-up services, such as monitoring the performance of the piles over time, to ensure that they continue to meet the required standards.


  1. Foundation Design: PIT is used to determine the integrity of deep foundation piles, including drilled shafts, cast-in-place piles, and driven piles, and to ensure that they meet the required design specifications.
  2. Quality Control: PIT is used during the construction of deep foundation piles to detect any issues or defects, ensuring that the piles are constructed to the required standards.
  3. Risk Assessment: PIT is used to assess the risk associated with existing piles, such as those in aging infrastructure or areas prone to natural disasters, such as earthquakes.
  4. Retrofitting: PIT is used to evaluate the effectiveness of retrofitting measures on existing piles to increase their load-bearing capacity or address any damage or defects.
  5. Forensic Investigation: PIT is used to investigate the cause of foundation failure or other issues in deep foundation piles, providing insight into the root cause of the problem and recommendations for remedial measures.
  6. Monitoring: PIT is used to monitor the performance of piles over time, providing data on their integrity and identifying any potential issues before they become serious problems.
