Physical exploration service "Resistivity Tomography"

Physical exploration service "Resistivity Tomography"

Improved analysis accuracy is expected compared to high-density resistivity electrical surveys conducted on the surface!

We offer "resistivity tomography," which involves arranging electrodes to surround the target exploration area using the surface and boreholes for measurements. By conducting multiple measurements, it is possible to assess the effectiveness of ground improvement based on changes in resistivity and to estimate the locations of permeable cracks using tracers. 【Features】 ■ Improved analysis accuracy is expected compared to high-density resistivity electrical surveys conducted on the surface. *For more details, please download the PDF or contact us.

Soil and groundwater contamination remediation technology "PRB method"

Soil and groundwater contamination remediation technology "PRB method"

A purification technology that utilizes the natural flow rate of groundwater to decompose VOCs within walls.

The "PRB method" involves the installation of a permeable reactive barrier (PRB) downstream of contaminated groundwater to prevent the spread of contamination. After the installation of the PRB, groundwater monitoring becomes the primary task, and it is maintenance-free. Additionally, the development of a construction method using a three-axis auger eliminates the need for retaining wall construction, making it applicable even to deep contaminated groundwater (up to 40 meters underground). 【Features】 ■ Maintenance-free (only monitoring is conducted) ■ Does not hinder the natural flow of groundwater ■ Reliable diffusion prevention measures ■ Applicable to deep contaminated groundwater as well *For more details, please download the PDF or contact us.

[ER Ground School] Session 1: Understanding Ground Conditions for Residential Land to Prevent House Tilting

[ER Ground School] Session 1: Understanding Ground Conditions for Residential Land to Prevent House Tilting

Features of the ground company and ground insurance/guarantee company you want to choose! The important thing is to compare each item!

The ER Ground School is a ground course for small-scale buildings, delivered in collaboration with a ground consultant (representative of Blue Sage Co., Ltd.) and Earth Relations. The first session will clearly explain "The Concept of Residential Ground that Prevents House Tilting" through a PowerPoint video. "We see numerous ground accidents occurring every year, yet there are companies that have almost never caused an accident." "If you want to choose a company that does not cause accidents, focus on 'number of accidents' and 'accident rate.'" [Key Points of the Discussion] 1. The reason I want to convey this again = because ground accidents are not decreasing. 2. The concept of residential ground that prevents house tilting. 3. What considerations are being made to prevent accidents. *For more details, please refer to the related link page or feel free to contact us.

External wall sounding survey using rope access technology.

External wall sounding survey using rope access technology.

No scaffolding is required, so only inspections can be conducted! A method suitable for preventive maintenance of buildings.

We would like to introduce the exterior wall inspection survey using rope access technology. Since there is no need for temporary scaffolding, costs associated with scaffolding can be reduced. Repairs can also be carried out after the exterior wall inspection without the need for scaffolding. Additionally, with a flexible repair plan, the financial burden can be divided. Initially, only the severely damaged "sealing work" can be done, followed by "tile work" in the next term, and then "painting work," allowing for cost division. 【Features】 ■ Capable of conducting inspections on walls of buildings in narrow spaces ■ Suitable method for preventive maintenance of buildings ■ Inspections can be conducted without the need for scaffolding ■ Ideal for high-rise buildings, etc. *For more details, please download the PDF or feel free to contact us.

Preliminary survey

Preliminary survey

Measure the width, length, size, and depth of cracks, defects, and spalling using a crack scale!

The tapping survey is a method of investigation where specialized tools (tapping rods, tapping hammers) are used to strike walls and assess their condition based on the sound produced. Investigators work using both visual inspection and the pitch of the sound, and tactile examination is conducted simultaneously, allowing for a very accurate assessment of the external wall's condition. The accuracy of the survey is influenced by the skill of the investigator, which is why our company provides training to rope access engineers aimed at standardizing skills and further improving their expertise, thereby enhancing the uniformity of inspections. 【Features】 ■ Assessing the condition by striking the wall with specialized tools (tapping rods, tapping hammers) and analyzing the sound ■ Investigators work using both visual inspection and sound pitch ■ Tactile examination is conducted simultaneously, allowing for a very accurate assessment of the external wall's condition ■ Measuring the extent of detachment, crack width and length using a crack scale, and assessing the size and depth of defects and spalling *For more details, please download the PDF or feel free to contact us.

[Case Study] Television Program Production Company

[Case Study] Television Program Production Company

We will introduce an example of distributing a survey to areas that cannot be reached through street interviews!

We conducted a survey using "Surveyloid," which allows for easy online surveys for respondents across the country, to gather information beyond our immediate surroundings. Here, we present a case study from a television production company. The purpose was to distribute a survey to areas where street interviews cannot be conducted, and we aimed to conduct a survey on "favorite celebrities" to announce the differences in popularity and reasons for preference by region within the program. "We are required to create content within a very tight timeframe for television production, but this product allowed for quick data collection, giving us time to create our presentation, resulting in a satisfactory outcome," was the feedback we received. 【Survey Overview】 ■ Survey Purpose: Research on "favorite celebrities" ■ Survey Method: Internet survey ■ Target Participants: Ages 20-69 / Male and Female / Residents of the Tokyo metropolitan area (Saitama, Chiba, Tokyo, Kanagawa) ■ Number of Responses: 100 from each prefecture (total of 400 samples) *For more details, please refer to the related links or feel free to contact us.

Does the ES survey improve company sales? Introducing implementation methods and question templates.

Does the ES survey improve company sales? Introducing implementation methods and question templates.

We will also introduce the purpose of conducting the ES survey and the benefits gained from increasing employee satisfaction!

An ES survey (Employee Satisfaction Survey) is a survey that measures the satisfaction levels of employees regarding various aspects surrounding their work, such as job content, workplace environment, organizational culture, and treatment. As various work styles, including side jobs and freelancing, are on the rise, employee satisfaction with their companies is an important factor in reducing turnover rates and improving productivity. Therefore, many companies conduct ES surveys. By understanding their own challenges through the ES survey and implementing appropriate measures, companies can create a better working environment for employees, leading to improved performance. *For more detailed information, please refer to the related links.
