Pile Cross Hole Sonic Logging Test

Pile Cross Hole Sonic Logging Test
Cross Hole Sonic Logging (CSL) is a non-destructive technology for determining the integrity and consistency of concrete in bored piles and drilled shafts. This test, performed in accordance with ASTM D6760, consists of transferring ultrasonic pulses between access tubes inserted in the pile. By monitoring wave velocity and energy loss, CSL finds abnormalities like cavities, honeycombing, or poor-quality concrete deep into the pile. The test is particularly useful in large-diameter piles where concrete quality is crucial. It assures structural soundness prior to superstructure development, reducing the risk of costly delays or failures caused by concealed faults.

Advantages of Pile Cross Hole Sonic Logging Test:

• Detects internal flaws, such as voids and segregation.
• Offers real-time statistics about concrete uniformity.
• Non-destructive and extremely accurate.
• Suitable for big, important structural piles.
• Helps to provide construction quality assurance.
• Compliant with ASTM D6760.
