Proposal for Piping Inspection

Proposal for Piping Inspection

Would you like to have a health check for your pipes? It's essential to first investigate the current condition of the pipes for issues like clogs and corrosion!

Circulating within the building, the plumbing for water supply and drainage can be likened to "blood vessels" in a person. Just as human blood vessels and building plumbing age (deteriorate over time), they can develop various troubles. To continue using the "plumbing," which is also the blood vessels of the building, it is important to conduct regular health check-ups to prevent troubles before they occur. Additionally, maintenance and inspection of the exterior drainage are also important. Our company offers solutions from high-pressure cleaning to resolve blockages in drainage pits and pipes, as well as repair work for cracks. 【Investigation Methods and Points for Selecting Investigation Locations】 ■ Ultrasonic thickness measurement: Calculate remaining lifespan ■ Endoscopic inspection: Check the condition inside the pipes ■ X-ray investigation: Check the condition inside the pipes ■ Pipe removal inspection: Calculate remaining lifespan *For more details, please refer to the PDF document or feel free to contact us.

Proposal for Non-Destructive Testing

Proposal for Non-Destructive Testing

No need to worry about water outages or drainage restrictions! Ultrasonic thickness measurement, X-ray inspection, and endoscopic examination are effective.

In conventional deterioration surveys, the only method that allowed for estimating remaining life through thickness measurements and understanding corrosion conditions was destructive testing, specifically pipe removal inspection. However, pipe removal inspection has many limitations, such as water shutdowns, drainage regulations, and nighttime work restrictions. Our company offers a high-precision deterioration survey that combines various diagnostic methods to conduct non-destructive testing similar to pipe removal. Please feel free to contact us when needed. 【Features】 ■ By identifying areas of wall thinning through X-ray inspection, pinpoint thickness measurements are possible. ■ Thickness measurements are conducted after assessing the condition of the piping, making it easier to detect pitting corrosion. ■ High-precision survey data can be provided. ■ No restrictions on working hours (nighttime). ■ There are no water shutdowns or drainage regulations, allowing for uninterrupted use of equipment and reducing the risk of leaks. *For more details, please refer to the PDF document or feel free to contact us.

Investigation of causes through foreign matter analysis

Investigation of causes through foreign matter analysis

Small anomalies, big clues! By database-ing past cases, quick and accurate judgments are possible.

"Foreign substances" refer to things that are different from the norm. They are defined as strange items that cause discomfort, and foreign substance analysis can provide significant clues for identifying the causes of problems and resolving issues. Our company conducts water quality testing for drinking water, hot and cold water, and cooling water in-house. By performing on-site water quality tests alongside foreign substance analysis, we can verify whether foreign substances or problems are derived from water quality. Additionally, we conduct over 500 foreign substance tests annually, allowing us to create a database of past cases, which enables us to make quick and accurate judgments based on that data. [Features] - In-house water quality testing for drinking water, hot and cold water, and cooling water - In addition to analysis, we also perform cleaning of hot and cold water systems, and in cases of foreign substances caused by corrosion, we can propose cleaning or rust prevention agents - Extensive track record: conducting over 500 foreign substance tests annually *For more details, please refer to the PDF document or feel free to contact us.

Refraction method elastic wave exploration service "Refraction Tomography"

Refraction method elastic wave exploration service "Refraction Tomography"

Analysis using tomographic methods!

Our company proposes a method called "refraction tomography," which applies tomographic techniques such as CT scans in medical fields to conventional elastic wave exploration. Through special iterative processing, we determine the two-dimensional velocity distribution of the ground. Additionally, since the calculation accuracy is proportional to the amount of data, it is necessary to take measurement points densely. 【Application Fields】 ■ Site investigation: Classification of rocks and soil due to excavation difficulty ■ Slope disaster prevention and cut slope investigation: Estimation of the gradient of stable areas ■ Landslide investigation: Understanding the depth of moving soil masses ■ Shotcrete slope investigation: Assessing the weathering condition behind deteriorated shotcrete ■ Tunnel, dam, and natural rock mountain investigation: Rock classification based on velocity values *For more details, please download the PDF or contact us.

Soil and groundwater contamination remediation technology "DIM Method"

Soil and groundwater contamination remediation technology "DIM Method"

It is possible to uniformly and effectively mix iron powder into contaminated soil!

The "DIM Method" is a technology that directly mixes special iron powder for soil purification into the ground to clean contaminated soil affected by organic chlorinated compounds in situ. In addition to being able to directly access deep contamination sources, it can supply the required amount of iron powder in a dry form, making it less likely for ground softening to occur after construction. 【Features】 ■ Direct purification of contamination sources ■ Iron powder mixing is possible even for deep contamination ■ Since only iron powder is supplied in a dry form, ground softening is less likely to occur ■ Fundamental purification without excavation (no need for retaining wall work) *For more details, please download the PDF or contact us.

What is the realistic cost range for asbestos surveys before renovation?

What is the realistic cost range for asbestos surveys before renovation?

Get an idea of the costs! Let's achieve a safe and secure renovation.

For businesses considering renovation work, especially those living in older homes, you may be concerned about the issue of "asbestos." Asbestos poses a risk of health hazards if not properly handled, so it is essential to confirm its presence before starting any renovation work. This article will explain the costs related to asbestos that may arise during renovations, including their breakdown, market prices, and information on subsidies. Asbestos can occur not only in demolition and renovation work but also in partial renovations, so please read this regardless of the age of your building. *For more detailed information, you can view it through the related links.

Survey on the actual conditions of employees, including executives.

Survey on the actual conditions of employees, including executives.

Investigation to confirm the actual situation of employees engaging in misconduct.

We will conduct an investigation to collect evidence that can be submitted to lawsuits arising from customer information leaks (violations of the Unfair Competition Prevention Act) due to side jobs, as well as to internal board meetings, shareholder meetings, and disciplinary committees. If evidence can be collected, it will become a very effective tool later on.
