Crosshole Sonic Logging (CSL) is one of the most accurate pile integrity tests to determine the integrity of deep foundation elements. CSL sends ultrasonic pulses through the concrete from one probe to another probe present in a pile and detects …

Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of …

CSL testing is the go-to QA technique for newly cast concrete structures. CSL testing can be used as Single-Hole Sonic Logging (SSL) when access is limited to one tube or in conjunction with Crosshole Tomography (CT) to find out more information about defects.

Exams are intended to test a candidate’s knowledge of building code and general construction practices. This bulletin describes the process of registering for and taking the CSL exams. Follow these main steps if you wish to take a BBRS exam. Complete the exam registration form on Page 15 and mail it to Prometric.

Standards for the CSL method include ASTM D6760 for integrity testing of concrete deep foundations, ACI 228.2R for NDE applications, and FLH 521.830 for determining pulse velocity through concrete in drilled shafts.

Cross-Hole Sonic Logging (CSL) is a non-destructive testing technique that utilizes ultrasonic waves to evaluate the integrity of concrete in deep foundations, such as drilled shafts and cast-in-place piles.

The MA unrestricted CSL exam is an open book test consisting of 75 questions that you must complete in three hours. Candidates who earn a score of 70% or higher will receive a passing grade.
