Non-destructive Testing of Concrete Dam - Quality Control of Concrete Cracks

Non-destructive Testing of Concrete Foundations

This article presents a brief review on Non-Destructive Testing of Concrete Foundations. It also discusses how engineers can utilize NDT to assess defects such as cracking and voids, and the deterioration mechanisms such as alkali-silica reactions, and corrosion of steel reinforcement. Concrete foundations are a key component in

Non-destructive Testing for Structural Condition Assessment

Non-destructive Testing for Structural Condition Assessment Structural Condition Assessment usually refers to the process of collecting observations and data about the existing condition of the structure through systematic and scientific methods. According to the Professional Engineers Ontario Guideline for “Structural Condition Assessment of Existing Buildings and Designated Structures” (PEO, Nov 2016), structural condition assessment are within

Quality Control of Concrete Caissons

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

What is Crosshole Sonic Logging?

The Crosshole Sonic Logging (CSL) or Ultrasonic Crosshole Test is a widely used non-destructive test for assessing Pile Integrity and quality control of drilled shafts (piles). CSL test is a variation of Ultrasonic Pulse Velocity. In theory, the pulse velocity in concrete is a function of the modulus of elasticity,

Condition Assessment of Parking Structures

Parking garages require routine inspection and maintenance to ensure they remain safe and operational. Whether it is public parking in extremely busy downtown area or a private condominium structure, proper maintenance is needed to keep them safe. The importance of parking garages is often ignored, simply because

3 Methods to Detect Voids under Concrete Slabs

In this article, we will review 3 non-destructive testing and evaluation methods for detecting voids under concrete slabs. We will review Ground Penetrating Radar, Ultrasonic Pulse Echo, and Impact-Echo/Impulse-Response methods for evaluating the location and extent of voids under concrete slabs and pavements. Voids Under Concrete Slabs

Non-destructive Evaluation for Precast Concrete

Precast concrete elements are usually manufactured and cured in a controlled environment. This controlled process results in high quality and consistency of the end products. However, construction errors, formwork issues, and damages during transportation and installation can impact the quality, and integrity of these precast elements. Non-destructive
