Distributed measurements of temperature in drilled or bored pile foundations to assess the integrity of the curing concrete have become increasingly common in the past decade. These methods have the advantage of detecting significant anomalies inside and outside of the reinforcing cage as the initial hydrating of the cement in the concrete generates heat. Conditional acceptance or further review of the foundation can be obtained within one to two days of casting. More recently, these techniques have been applied to diaphragm wall panels used in tunnels and other building construction. The expected trends in the temperature versus depth data are reviewed, indicating the consistency of measurements on the wall faces and cooler zones at the corner. An example showing the detection of local concrete cover changes and potential inclusions or non-uniformities at the bottom of the panels are also presented.
