Introduction The tragic collapse of the 12-Storey Beachfront Condo in Florida has reignited discussion around proper inspection and maintenance of buildings in North America. At the moment there is limited information available about the condition of the Florida building prior to its collapse with the inspection report by Morabito Consultants being one of the only reports to provide any insight. It will take some time for structural forensic experts to… Read More »Why Buildings Collapse & How We May Prevent It
Quality control of Concrete Caissons is a challenging task. Engineers, and contractors rely on experience and well-established procedures and test standards to verify the strength, and consistency of pile materials. Non-destructive testing help reveal potential defects that might have happened during pile casting (in the case of cast-in-place piles), or transportation and installation (in the case of precast piles).

This article describes the applications of non-destructive testing (NDT) and evaluation in the inspection and condition assessment of Concrete tanks. Depending on their particular application, concrete tanks are exposed to water, wastewater (sewer), and other aggressive chemicals. This can result in deterioration of concrete during its life cycle. Non-destructive Testing can help engineers in evaluating the location and extent of defects. Share on linkedin Share on facebook Share on twitter… Read More »Non-Destructive Testing of Concrete Tanks

A multi-technology approach using different Nondestructive Testing (NDT) technologies is becoming the new standard in structural condition assessment. Ground Penetrating Radar has proved to be an effective method in collective key information about the structural details, however, this interesting technology comes with inherent limitations. It is important to develop a good understanding of the capabilities of GPR, and cover its shortcomings with complimentary methods such as the Ultrasonic Pulse based… Read More »How to use GPR in Structural Assessment?
Nondestructive Testing have great applications in the concrete construction industry. It helps designer, construction engineers, and contractors the ability to verify the quality and integrity of built structures, identify and quantify potential defects, and record as-built condition like never before. The author has several years of combined research and industrial experience in helping construction industry in Canada, and has witnessed how NDT can help identify and quantify location and extent of potential… Read More »Applications of Nondestructive Testing in Concrete Construction
Crosshole Sonic Logging is an effective nondestructive testing method for deep foundations. Developed based on the principles of ultrasonic pulse velocity (UPV) test in concrete, the test can address some of the practical limitation that come with length/diameter (i.e. in low strain pile integrity test). The test can be used to collect precise information on the quality and integrity of concrete at different depths. Certain combination of ultrasonic probes enables… Read More »What is Crosshole Sonic Logging?
