The Crosshole Sonic Logging (CSL) method is a non-destructive testing technique for bored piles, used to evaluate the homogeneity and integrity of concrete along the pile shaft. It detects defects such as aggregate segregation, concrete voids, soil/rock inclusions, or variations in pile cross-section. This is a mandatory requirement in the acceptance process for construction projects with pile foundations, especially large bridge structures and high-rise buildings, to ensure foundation safety.
