What is CSL Testing & Why is It Important?
CSL testing (Crosshole Sonic Logging Test) is a non-destructive testing method used to assess concrete quality in deep foundations. It ensures that drilled shafts and piles are free of voids, defects, and other flaws that could compromise structural integrity.
The CHUM system by Piletest is an industry-leading CSL test system designed for accurate and high-resolution cross hole ultrasonic tests on deep foundations.
CHUM is Designed For:
-
Cross Hole Sonic Logging Test for Piles – Detects flaws, voids, and anomalies in concrete piles.
-
High-Resolution 2D & 3D Tomography – Provides clear visualization for defect analysis.
-
Cross Hole Ultrasonic Test (CSL Test) Standrad Compliance – Meets ASTM D6760 & AFNOR NF P 94-160-1.
-
Fast & User-Friendly Operation – Minimal training is required—top performance enabling high-speed data collection.
Industry Compliance & Regulations:
-
ASTM D6760-16 – Standard Test Method for CSL Testing of Concrete Foundations.
-
AFNOR NF P 94-160-1 – International standard for crosshole sonic logging test procedures.
-
Best CSL on the market – It delivers industry-leading accuracy & reliability.

How Does a
Cross Hole Sonic Logging Test Work?
The CHUM system operates using the Cross Hole Sonic Logging (CSL) method, where ultrasonic pulses travel through water-filled access tubes embedded in the concrete. The wave’s arrival time and energy indicate concrete integrity.
Step-by-Step Process for a Cross Hole Sonic Logging Test:
-
Install Water-Filled Access Tubes into the Concrete Pile – Tubes are embedded before the concrete cures.
-
Lower CHUM Ultrasonic Transmitter & Receiver Probes – The probes travel through the tubes, scanning the pile.
-
When pulling back the sensors, measure Wave First Arrival Time (FAT) & Relative Energy (RE) – The concrete’s quality affects the ultrasonic wave behavior.
-
Analyze & Detect Defects – The CHUM CSL testing software processes the data in real time.
-
Generate 2D & 3D Tomography Models – Advanced visualization helps in understanding the internal pile flaws.
