Corrosion of Steel Reinforcement in Concrete: Detecting, Mapping, and Monitoring

February 08, 2023

The corrosion of reinforcing steel is a significant and preventable problem that shortens the useful lifespan of concrete structures. The mechanisms for its development and how it eventually damages the concrete structures it was designed to protect have been well-known for over 100 years. Similar to progressive disease, early detection and monitoring are the most effective strategies to minimize problems. Fortunately, innovative nondestructive instruments are making it easier and more efficient to find, follow, and repair corrosion before extensive damage occurs.

5 Concrete Strength Testing Methods – Non-Destructive

January 04, 2023

Testing the properties of hardened concrete is central to evaluating a structure, whether it is decades old or still under construction. In-place testing of concrete is a significant part of assessing an existing structure's safety and physical condition for routine maintenance before modifications. This blog post will discuss in-place and nondestructive methods and equipment to measure concrete strength.

Ground Penetrating Radar for Concrete Evaluation: What's the latest?

September 07, 2022

Ground Penetrating Radar (GPR) is a powerful tool for the nondestructive testing and evaluation of reinforced concrete. Next-generation refinements featured on these versatile new models from Gilson simplify the location and mapping of reinforcing steel bars, tendons, and other embedments while assessing homogeneity, measuring thickness, and detecting cracks, voids, and other discontinuities. GPR units connect wirelessly to Apple iPad? tablets for potent computing power, live 3D and Augmented Reality (AR) rendering, high-resolution display, and fast, easy upgrades. Encrypted Wi-Fi connection stores data in the cloud for instant sharing and collaboration.

Rebar in Concrete: Nondestructive Characterization of Reinforcing Steel

February 01, 2021

Advances in technology continue to refine concrete cover meters and rebar locators, which have been around for decades and used to locate and identify concrete reinforcing steel accurately. They are integral to nondestructive evaluations of reinforced concrete structures and pavements to prevent damage to the reinforcing steel within the structure when drilling or cutting reinforced concrete. This blog post explores the features and capabilities of some of these popular instruments.
