an anomaly in the reflectogram can be caused by necking if the curve deflects first in the direction of the hammer blow, and then in the opposite direction before returning to normal. in the European usage, the hammer blow is plotted downwards. thus a necking in the pile causes the reflectogram to deflect first downwards and then upwards. if the anomaly is in the upper half of the pile, it can repeat itself one or more times, depending on the pile profile and soil properties. all consequent reflections will have the same characteristics as the first one - downward and then upward.

Why top layer of concrete pile is broken?
The top layer of a concrete pile could be broken due to several factors, such as poor construction practices, overloading, structural defects, or exposure to harsh environmental conditions like freeze-thaw cycles or corrosion. It is essential to properly assess the cause of the breakage to prevent further damage and ensure the structural integrity of the pile.

What is allowable eccentricity for pile?
Concrete piles cannot be driven at precise intended location; This is true for bored piles also. For practical reasons various country design codes restrict the permissible deviation. In Indian code this value is specified as 75 mm. This plays important role in pile-cap design. The deviation smaller than this will never be reported. So pile cap sizing needs to be based on the worst possible direction deviation. The pile eccentricity is one of the important aspects in pile cap shear strength calculation as well as pile cap reinforcement calculation.
