Non-destrcutive Testing- NDT Methods for Evaluation of Parking Garages can help improve the quality of routine inspection and maintenance. Parking garages require routine inspection and maintenance to ensure they remain safe and operational. Weather it is a public parking in extremely busy downtown areas, or a private condominium structure, proper maintenance is needed to keep Read more about NDT Methods for Evaluation of Parking Garages[…]

Corrosion Monitoring of Reinforced Concrete Structures

Corrosion Monitoring of Reinforced Concrete Structures

A corroded structure (whether it is a bridge, or a jetty, or a simple ramp) could be scary for many people. Imagine yourself driving along the Gardner Express (Downtown Toronto), or the highway 40 (Montreal), and all of a sudden, a piece of concrete falls onto your car, breaking the windshield. Feels scary? Indeed! A Read more about Corrosion Monitoring of Reinforced Concrete Structures[…]

Condition Survey for Bridge Decks

4 Methods of Condition Survey for Bridge Decks

Exposed Concrete Decks suffer from various deterioration mechanisms; i.e. freezing and thawing, corrosion. The most significant consequence is the delamination of concrete, which could eventually trigger other damage mechanism, such as corrosion. The maintenance of deck slabs is quite challenging mainly because it normally involves large areas; In many cases, closing the deck to traffic Read more about 4 Methods of Condition Survey for Bridge Decks[…]

Reuse of Existing Piles Feature

Reuse of Existing Piles – How NDT Can Help

Safety, reliability and satisfactory performance of structures require a well-planned maintenance program, as well as remedial actions in short and mid-term. Existing structures that are designed in accordance with older design codes or were built by older construction practices may need to be extensively repaired, rehabilitated, or replaced within the next few years. The remedial Read more about Reuse of Existing Piles – How NDT Can Help[…]

NDE of Concrete Dams

4 Methods for Nondestructive Evaluation of Concrete Dams

Appropriate operation and maintenance of concrete dam structures are essential to ensure the safety of the structure, and reducing risk. Concrete surfaces should be examined in a regular basis to identify spalling and deterioration due to weathering, or extreme stresses, or other physical, or chemical damage mechanism. Nondestructive Evaluation of Concrete Dams can provide useful information about the Read more about 4 Methods for Nondestructive Evaluation of Concrete Dams[…]

Crack Depth Measurement in Concrete-Feature Pic

3 Methods for Crack Depth Measurement in Concrete

Evaluation of existing surface cracks is normally done during the visual inspection of structures. Crack opening on the surface of concrete is normally measured using a crack gauge. Depending on the opening of the cracks on the surface, cracks can be described (as tiny as hairline, or cracks with a few millimeters opening); however, this Read more about 3 Methods for Crack Depth Measurement in Concrete[…]

Half Cell Corrosion Potential Mapping

Half Cell Corrosion Mapping for Concrete

Half Cell corrosion mapping is an effective method for assessing the severity of corrosion activity in concrete structures. It is the most well-known procedure to identify the likelihood of active corrosion; however, the test does not provide any information about the kinetics of corrosion activity. The easy and cost-effective procedure of the test makes it popular Read more about Half Cell Corrosion Mapping for Concrete[…]

ultrasonic testing of concrete

Ultrasonic Testing of Concrete

Ultrasonic Pulse Velocity (UPV) is an effective non-destructive testing (NDT) method for quality control of concrete materials, and detecting damages in structural components. The UPV methods have traditionally been used for the quality control of materials, mostly homogeneous materials such as metals and welded connections. With the recent advancement in transducer technology, the test has Read more about Ultrasonic Testing of Concrete[…]

NDT methods for Scanning Concrete Bridge Decks

What is the future of bridge deck scanning? What is beyond traditional scanning methods such as chain dragging? This article briefly describes application of NDT methods for scanning concrete bridge decks. Regular monitoring and maintenance of concrete bridge decks is a challenging task. The Inspection and monitoring of concrete bridge decks using traditional chain dragging Read more about NDT methods for Scanning Concrete Bridge Decks[…]

Acostic Emission Monitoring

Acoustic Emission Monitoring for Civil Infrastructure

Acoustic Emission is referred to the radiation of acoustic waves in solids as a result of damage or any irreversible change in its internal structure. Acoustic emission monitoring is well-known for its application in structural health monitoring of civil infrastructure. Structural Health Monitoring Health monitoring is a process of implementing inspection, evaluation, reaction, re-inspection and re-evaluation in Read more about Acoustic Emission Monitoring for Civil Infrastructure[…]
