A quick review of low strain impact tests for deep foundations, The IS code for pile integrity test is 14893
“Pile integrity is the qualitative evaluation of the physical dimensions, continuity of a pile, and consistency of the pile materials.”
Why do we need to test?
It is important to test pile because defects can occur during the construction and installation of the pile and also as a pile ages voids and cracks necking and soil inclusion can all impact the integrity of pile structure. Therefore, it is important to find proper tools for effective quality control and quality assurance of the pile unlike beams and columns piles are buried underground with only the pile heads accessible. Therefore developing a test method to assess the quality and integrity from the pile head is important and very useful.
