"Waterproof" and "Amajimai" I think the general public may not be familiar with the words "rain dance", but both are measures to prevent rain from entering the building. The big difference between these two is that "waterproofing" is a measure to prevent rainwater from entering, and "rain wrapping" is a measure to receive rainwater and let it escape. Both may be the most careful part when building a building in a rainy Japan. Language This page has been automatically translated. Please note that it may differ from the original contents.

We conducted an infrared thermography survey at the request of a contractor. In the same survey, it is said that it is not suitable for rain or after rain because it is not possible to conduct a survey if moisture adheres to the surface of the subject, but this survey was taken after waiting 2 hours after watering. Of course, the moisture on the surface is dry before shooting. On the back side (interface) of the tile, the part where the sprinkled water circulates and the part where it is not are clearly marked. You try a lot of things. Language This page has been automatically translated. Please note that it may differ from the original contents.

It's a continuation of yesterday! With infrared thermography surveys, it is possible to investigate not only leaks but also floating tiles. That's because even if there is water or air on the back of the tile, it looks almost the same, why? Because the surface temperature of the tile is different from the water and air trapped behind the tile, if this blue part is "Water!" or "It's the floating tile!" If you are told Why can you judge that by infrared thermography images? To be continued! Language This page has been automatically translated.

Of course, you can't check visually under the stretched tiles. There are many ways to tile it, but let's say you put a tile on a concrete wall with bond, and 10 years later two tiles fell off! One has bond on the back of a peeled tile, but no bond on the concrete The other has no bond on the back of the tile, but on the concrete wall Continue next time Language This page has been automatically translated.

Don't make the mistake of saying "water is blue" in thermal images. The temperature of water varies depending on the environment. Cold water, warm water, hot water, etc. Even if the thermographic image says "the blue part is water", don't take it for granted, especially if it's a tile finish.

What can be seen by visual inspection is... Small things Simply put, things that cannot be seen from below The upper part of the sash is not visible from below But that part is the part where there is a lot of deterioration Language This page has been automatically translated.

When the moisture content of three parts of the beam was measured, completely different values were detected. Since the value dropped from the back to the front, it is thought that the rainwater was flowing from the back to the front. Language This page has been automatically translated.
