Crosshole Sonic Logging (CSL) Test

In the high-stakes world of Philippine construction, the foundation is everything. Inch-On Materials Testing Laboratory provides high-precision Crosshole Sonic Logging (CSL) Testing to verify the structural integrity of newly cast drilled shafts, bored piles, and deep foundations. By looking deep inside the concrete, we ensure your project stands on a foundation free of hidden defects and structural weaknesses.

Core Testing Services

1. Ultrasonic Pulse Velocity Analysis

2. Comprehensive Access Duct Mapping

Testing between adjacent tubes.

Cross-scanning to pinpoint the exact coordinates of defects.

3. Defect Identification & Profiling

  • Identifying where soil has intruded into the shaft.

Detecting areas of low-density or poorly consolidated concrete.

Locating significant breaks or debris inclusions.

Why Our Testing Matters

In the Philippines, where seismic activity and soil variability are constant challenges, a “stiff” pile isn’t enough. Unlike Low Strain Impact Integrity Testing, CSL is not limited by pile length or soil friction, providing a “clear view” through the entire cross-section of the foundation.

Our detailed sonic profiles and “waterfall” plots help Contractors, Developers, and Engineers in the Philippines to:

Ensure your project meets the strict standards of the Department of Public Works and Highways.

Identify "soft spots" before they become structural failures.

Gain the peace of mind that your deep foundations are solid from the core to the surface.
