On-Site Evaluation of Concrete Strength

5 Methods for On-Site Evaluation of Concrete Strength

On-site Evaluation of Concrete Strength is a main challenge in the condition assessment of existing infrastructure, or the quality control of new construction. Owners, maintenance managers of such existing concrete structures normally prefer non-destructive and non-intrusive methods to avoid further damage to an already struggling structure. In construction projects, switching to non-destructive means less intervention, Read more about 5 Methods for On-Site Evaluation of Concrete Strength[…]

Cold Joints in Concrete Beams

Non-Destructive Evaluation of Cold Joints in Concrete

This technical note briefly discusses non-destructive evaluation of cold joints in concrete structures. We will review how structural engineers and quality control laboratories can utilize NDT methods to assess the quality and integrity of concrete on or around the cold joint. What is Cold Joint in Concrete? Cold joints in concrete primarily happen when there Read more about Non-Destructive Evaluation of Cold Joints in Concrete[…]

Non-Destructive Testing of Wind Turbine Foundation

Non-Destructive Testing of Wind Turbine Foundation

Over the past decade, Canada has heavily invested in wind energy, increasing its annual capacity from nearly 2,000 MW in 2008, to 13,000 MW in 2019. That is enough to power approximately 3.3 million homes – 6% of our country’s electricity demand (Canadian Wind Energy Association, 2019). There are 299 wind farms operating from coast Read more about Non-Destructive Testing of Wind Turbine Foundation[…]

5 Integrity Problems of Concrete Piles

5 Integrity Problems of Concrete Piles

Deficiency of concrete materials is a common problem in Bored Pile construction. This is mainly because integrity problems of concrete piles can affect the load bearing capacity and load distribution properties. Piles and deep foundations transmit top structure loads to strong substrate through friction and/or standing on bed rock. This load transmission is performed effectively when no Read more about 5 Integrity Problems of Concrete Piles[…]

Reuse of existing piles and deep foundations

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[…]

What is Pile Integrity Test _

What is Pile Integrity Test ?

Construction and installation of concrete piles and deep foundations is a challenging task. Problems can occur during the process, which in turn results in defects in pile components. Pile formation problems, Concrete faults, and reinforcement installation issues are among the most common problems. The resulting defects can negatively impact the durability and mechanical performance of Read more about What is Pile Integrity Test ?[…]
