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.
