Ground-based infrared survey

Ground-based infrared survey

Captured the condition of the exterior wall with a higher surface temperature compared to normal areas using an infrared camera!

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.

Infrared survey using drones

Infrared survey using drones

The condition of the exterior walls with temperature differences is captured by a drone! It is now possible to diagnose even high-rise exterior walls.

We will introduce infrared surveys using drones.

【Business Content】Exterior Wall Inspection Survey

【Business Content】Exterior Wall Inspection Survey

Access to any work area is possible! Safety measures are being implemented by everyone.

We would like to introduce our "Exterior Wall Inspection Survey." Not only do we perform high-altitude work using ropes, but we also own upright lifts and lightweight aluminum scaffolding, allowing us to carry out work efficiently and appropriately according to the location. Additionally, we have holders of the international qualification "IRATA," who provide guidance on rope installation and other related tasks. 【Services Offered (Partial)】 ■ Work in confined spaces ■ Leak inspection ■ Tile work ■ Exterior wall painting ■ Caulking work *For more details, please download the PDF 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.

Non-scaffolding method for exterior wall inspection that eliminates the need for scaffolding, enabling cost reduction and shortening of construction period.

Non-scaffolding method for exterior wall inspection that eliminates the need for scaffolding, enabling cost reduction and shortening of construction period.

No scaffolding is required, so inspections can be conducted alone! A suitable method for preventive maintenance of buildings! The need for scaffolding installation and dismantling is eliminated, allowing for cost reduction and shortened construction periods.

We would like to introduce the wall inspection survey using rope access technology. Since scaffolding is not required, costs associated with scaffolding can be reduced. Repairs can also be carried out after the wall inspection without the need for scaffolding. Additionally, with a flexible repair plan, the financial burden can be divided.
