Impact Echo is an acoustic sounding technique. In this article, 6 widely-used non-destructive testing methods will be discussed with the aim to locate defects in concrete. Foundations such as piles or builk footings can also house defects. Air voids or cracks interrupt or delay the passage of sound and make ultrasonic testing methods valuable and reliable. Structural support is also a concern with scouring of supporting earth due to underground water flow a risk.ĭefect location testing systems often take advantage of different forms of sonic testing. Once a structure is constructed and accepted it may still develop defects, long term corrosion can cause delamination and spalling damage to structures.
Visual inspection will not locate hidden flaws in a structure or measure the extent a visible defect projects into the structure. During construction, bad consolidation can leave air voids, honey combing, or concrete may crack during curing. Register now! Defect Location in Concreteĭefects in concrete can occur during and after construction.

We launch May 11th at 12.30 pm with a presentation on the Non-Destructive tests mentioned in the recently released Bridge Code section AS 5100.8. We are planning to host regular online presentations on important areas of non-destructive and materials testing. PCTE is pleased to be launching our YouTube Live channel. The sieves comply with the specifications set out by the world's most demanding Standards and we offer a variety of types and sizes. We are excited to announce the arrival of our new Laarmann sieve stock. It will also provide a brief explanation on the processing of GPR data. This blog will discuss the non-destructive testing methods that can be used to locate defects in concrete.
