Thermal Integrity Profiling (TIP) Services

SACL’s TIP uses embedded Thermal Wire® cables and Thermal Acquisition Ports (TAPs) to capture the thermal prole of curing concrete foundations. By monitoring temperature variations along the full length of a drilled shaft or pile, TIP identies anomalies in concrete cover, shaft geometry, and reinforcement cage positioning, all without the need for embedded access tubes.

Key Benefits

  • Complete Coverage: Evaluates the full shaft, including zones outside the rebar cage.
  • Early Testing: Data can be collected 12–48 hours after casting, accelerating decision-making.
  • Defect Detection: Spots necking, bulges, inclusions, and reinforcement deviations via localized temperature changes.
  • Non-Destructive: Maintains shaft integrity and avoids impact on construction schedules.

Why Choose SACL for TIP?
Our remote service model and national network of in-person engineers ensure fast results and lower costs. Backed by decades of deep foundation expertise, SACL delivers clear, actionable insights that help you meet design specications and maintain project timelines.

Frequently Asked Questions

Thermal Integrity Profiling (TIP) and Cross-Hole Sonic Logging (CSL) are both methods used to evaluate the integrity of deep foundations, but they operate differently:

  • TIP: Uses the heat generated by curing concrete to detect anomalies. Sensors measure temperature variations along the pile, identifying potential defects like voids or inclusions based on deviations from expected temperature profiles. This test also allows to assess the concrete cover by detecting deviations of the reinforcing cage.
  • CSL: Involves passing ultrasonic pulses between pairs of access tubes installed in the pile. By analyzing the travel time and signal strength of these pulses, CSL can detect anomalies within the pile core defined by the positioning of the access pipes within the cage. This test does not report on concrete outside the core.
