Uncovering Hidden Defects: Non-Destructive Testing in Drilled Shafts (Webinar)

In Uncovering Hidden Defects: Non-Destructive Testing in Drilled Shafts, you'll learn ...

• The history and development of drilled shafts
• Typical construction challenges—ranging from alignment and concrete placement errors to more serious structural anomalies.
• The most up-to-date non-destructive testing methods that enable engineers to assess internal conditions without damaging the structure.
• Corrective actions and preventative strategies—from basic repair techniques to more advanced remediation approaches.

Overview

---

This webinar is designed to equip engineers with the critical knowledge needed to identify and address issues that may arise during drilled shaft construction. Drilled shafts are essential foundation elements in major infrastructure projects, but without proper construction practices and monitoring, defects can compromise their performance.

The webinar begins with an overview of the history and development of drilled shafts, followed by a detailed discussion of construction methods. Attendees will explore typical construction challenges—ranging from alignment and concrete placement errors to more serious structural anomalies. The webinar categorizes these defects and introduces the most up-to-date non-destructive testing methods, including crosshole sonic logging, crosshole tomography, Sonic Echo, and Thermal Integrity. These tools enable engineers to assess internal conditions without damaging the structure.

Additionally, the webinar covers both corrective actions and preventative strategies—from basic repair techniques to more advanced remediation approaches. Engineers will gain practical insight into effective mitigation planning that enhances reliability and ensures the long-term performance of drilled shafts.
