We will introduce infrared surveys using drones. Exterior wall tiles and mortar are warmed by solar radiation and outside temperatures, and that heat is transmitted to the structure (thermal conduction). However, if there is delamination in the exterior wall tiles or mortar, creating an air layer, the heat does not transfer to the structure, leading to a tendency for the surface temperature to be higher compared to normal areas. By capturing the state of the exterior wall with such temperature differences using a drone, it is possible to diagnose even high-rise exterior walls. [Features] ■ By capturing the state of the exterior wall with temperature differences using a drone, it is possible to diagnose high-rise exterior walls. *For more details, please download the PDF or feel free to contact us.

We would like to introduce infrared surveys from the ground. When exterior wall tiles and mortar are warmed by sunlight or outside temperatures, that heat is transmitted to the structure (thermal conduction). However, if there is delamination in the exterior wall tiles or mortar, creating an air layer, the heat does not transfer to the structure, resulting in a tendency for the surface temperature to be higher compared to normal areas. By capturing the state of the exterior wall with such temperature differences using an infrared camera, exterior wall diagnostics can be performed. 【Features】 ■ By capturing the state of the exterior wall with temperature differences using an infrared camera, exterior wall diagnostics can be performed. ■ It is effective when you want to understand the situation, even if roughly. *For more details, please download the PDF or feel free to contact us.

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.

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.

Special high-altitude techniques are completely different from rope access techniques. Rope access techniques are an absolutely safe and wonderful method based on the premise of two-point anchoring. They allow for safe, rapid, and reliable movement not only vertically but also freely in all directions. As long as two-point anchoring is secured, it is a technique that has been proven over many years of safety records to never result in a fall. 【Features of Rope Access Techniques】 ■ The fundamental principle of "two-point anchoring" ■ Complete implementation of "rope checks," "operation confirmations," and "pre-load tests" ■ Safe, rapid, and reliable access to any height or difficult location ■ Ability to move freely not only vertically but also in all directions ■ Almost only labor costs, minimal traffic regulation, and overwhelmingly low cost *For more details, please download the PDF or feel free to contact us.
