Concrete Bridge Condition Survey Service

Concrete Bridge Condition Survey Service

We will investigate the condition of the concrete bridge through physical exploration.

Our company conducts concrete bridge condition surveys using physical exploration methods. Infrared thermography allows us to investigate areas that are otherwise inaccessible. By identifying the differences in radiative temperatures between deteriorated and sound areas, we can pinpoint the deteriorated sections and use this as a basis for detailed investigations. Additionally, we measure the minute vibrations from impacts using elastic wave tomography to determine the distribution of elastic wave (P-wave) velocities within the concrete. We evaluate the condition of the measurement points based on the correlation between the condition and the elastic wave velocity. Using RC radar, we non-destructively detect deformations within the concrete that cannot be visually confirmed. Defects, voids, foreign objects, etc., appear as abnormal reflection patterns of electromagnetic waves. *For more details, please download the PDF or contact us.*

Technical Document: Oil Pollution Control Technology for a Decarbonized Society

Technical Document: Oil Pollution Control Technology for a Decarbonized Society

A Japanese-origin activated carbon purification method for a decarbonized society! Addressing oil contamination with the Smart Cap method, an activated carbon purification technology!

[New Oil Pollution Control Technology for a Decarbonized Society] ■ Following the Japanese government's "2050 Carbon Neutral (CN2050)" initiative in 2020, there has been a transformation in corporate awareness towards a decarbonized society. ■ The social implementation of a unique and highly effective "Negative Emission (NE) technology" that stores "biochar" in the ground and agricultural land, strongly promoting CN2050, has begun. ■ Since the postponement of establishing soil oil pollution concentration standards in the past, Japan's development of oil pollution purification technology has been in decline, peaking 20 years ago. ■ The "Activated Carbon Bioremediation Technology," which is also an NE technology, progresses with bioremediation after the sensory values of oil pollution are cleared early on. As a result, the challenge of determining the endpoint of purification, which was difficult with bioremediation, has been overcome, transforming it into a technology with excellent reliability for site management. ■ In Japan, there is a similar activated carbon purification technology known as the "Smart Cap" method, which has been proven to be applicable to oil pollution control as VOC purification technology. *For more details, please contact us or view the PDF download.

Non-destructive testing: Visible image method for crack investigation

Non-destructive testing: Visible image method for crack investigation

Automatically extract "crack width" and "crack length"! No need to set up scaffolding for inspection!

Visible cracks and the occurrence of bulging are the first steps of deterioration and deformation. The digital imaging method automatically extracts crack width and length, and CAD output is also possible. Cracks are automatically extracted from the captured digital images. It can automatically extract "crack width" and "crack length." Since crack extraction is analyzed from the captured images, there is no need to set up scaffolding for inspection as long as the shooting location can be secured. 【Advantages】 ■ Safety (non-contact): Diagnosis can be performed from a safe location. ■ Record: Deterioration conditions can be visualized with thermal images, and image data can be saved for analysis. ■ Economic (short time): No need for temporary structures such as scaffolding or gondolas. *For more details, please contact us.
