TRAWE List of Products and Services

When an earthquake occurs, many people first worry about the collapse of the building itself or damage inside. However, what should be noted in building management is the "external damage" such as exterior wall tiles, mortar, sealing, and exterior materials. Even if there is no significant damage to the entire building, the shaking from the earthquake can gradually put stress on the exterior walls. Particularly in existing buildings, areas where the adhesive strength has already decreased due to aging or where fine cracks have developed may progress to detachment or peeling as a result of the earthquake. The Ministry of Land, Infrastructure, Transport and Tourism also emphasizes the importance of maintaining a state without damage that poses a risk of falling, by checking for "cracks, defects, and detachment" on the exterior walls. Even if there seems to be no problem on the surface, the adhesion between the tiles or mortar and the substrate may have been compromised internally. Using rope access, we can conduct high-altitude exterior wall inspections without setting up scaffolding. We also respond to inspections of specific areas of concern, tapping surveys, and emergency repairs. A "precautionary check" after an earthquake can prevent major accidents before they happen. For exterior wall inspections and repairs in Tokyo, Chiba, Saitama, and Kanagawa, please consult TRAWE.

The rooftop is the part of a building that is most susceptible to the effects of rain, wind, and ultraviolet rays. However, unless there are scheduled inspections, there are not many opportunities to check it, and before you know it, the waterproofing layer may have deteriorated. If left in a deteriorated state, it can lead to leaks and internal corrosion of the building, causing a decrease in the overall durability of the structure. If you notice any of the following symptoms, please consult and consider waterproofing work for your rooftop: - Cracks on the rooftop - Blistering or peeling of the waterproofing layer - Occurrence of leaks - Poor drainage or water pooling - More than 10 years have passed since installation We will assess the building's purpose and the condition of the existing waterproofing layer and propose the most suitable method.

As of 2026, significant changes are occurring in the real estate and construction industries that property owners and management companies cannot afford to overlook. These changes are the "rising repair costs" and "shortage of construction companies." In recent years, the construction industry has been facing a shortage of skilled workers, an aging workforce, and a decrease in personnel due to work style reforms. Additionally, the prices of materials, logistics, and fuel continue to soar. Furthermore, due to uncertainties in overseas situations and the depreciation of the yen, the prices of materials necessary for building repairs, such as paints, sealing materials, waterproofing materials, and steel products, are on the rise. As a result, even for the same repair work as before, there are increasing cases nationwide where: - Estimates are higher than a few years ago - There is a wait of several months before construction can begin - Small-scale projects are being declined - Emergency responses cannot be provided immediately Three risks of postponing repairs: 1. Secondary damage from leaks and water intrusion Neglecting exterior wall cracks, deteriorating sealing, and broken waterproofing layers can lead to internal corrosion and water damage. 2. Negative impact on occupancy rates and rental prices Deterioration of the exterior and aging of common areas lower the impression during viewings and increase the risk of vacancies. 3. Future increase in repair costs Areas that should have been resolved with minor repairs can often escalate into major renovations.

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.

• Structural Survey

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.
