Pile integrity testing using low-strain tests such as the TDR (Transient Dynamic Response) method, is a rapid way of assessing the continuity and integrity of concrete piled foundations. The test measures: pile length, or depth to anomalies; pile head stiffness; pile shaft mobility, which is dependent on pile section and concrete properties
Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage.

High strain dynamic testing is a method of testing deep foundations to obtain information about their capacity and integrity, and in some cases, to monitor their installation. It is codified by ASTM D4945-12 - Standard Test Method for High-Strain Dynamic Testing of Piles.
A procedure for ultrasonic testing is outlined in ASTM C597 - 09. [9]In India, till 2018 ultrasonic testing was conducted according to IS 13311-1992.From 2018, procedure and specification for Ultrasonic pulse velocity test is outlined in IS 516 Part 5:Non destructive testing of concrete Section 1:Ultrasonic Pulse Velocity Testing.
It is standardized by ASTM D7949 - Standard Test Methods for Thermal Integrity Profiling of Concrete Deep Foundations. The testing method was first developed in the mid 1990s at the University of South Florida. [1] [2] It relates the heat generated by curing of cement to the integrity and quality of drilled shafts, augered cast in place (ACIP ...
Weight machines get a bad rap, but are perfect for beginners to boost form and target muscles safely. Plus, a full-body workout programmed by a pro.
Foundation integrity testing is the non-destructive testing of piled foundations.It was first used in the late 1960s, and has been developed over time by many companies. Three organizations supply a majority of the test equipment in use: CEBTP (Centre Expérimental de Recherches et d'Etudes du Bâtiment et des Travaux Publics) in Europe; Integrity Testing in Asia and Australia: and by GRL ...
