Non-destructive integrity testing for deep foundation elements
D.W. Kozera, Inc. offers Crosshole Sonic Logging (CSL) services to assess the structural integrity of drilled shafts, auger cast piles, and other cast-in-place concrete foundation elements. CSL is a proven non-destructive testing method that identifies potential anomalies such as voids, necking, honeycombing, or poor concrete bonding. These issues are often invisible from the surface but critical to long-term performance of deep foundations.
Our experienced technicians perform CSL testing and deliver clear, actionable reports that meet the needs of engineers, contractors, and project owners. We work closely with construction teams to coordinate testing at the appropriate stage and provide timely data to support acceptance decisions and reduce project delays.
