Survey Methodology


《Step1》
 Infrared thermography photography survey.

This survey checks the temperature distribution of the building surface and confirms the moisture that retains inside.
Check the water retention distribution and water immersion direction that cannot be visually checked.
The purpose is to narrow down the scope of the survey and develop a research plan.

*This is only a stand-alone investigation of infrared thermography photography, and the cause cannot be identified.
Analyze the image and pass the baton to the hydropath survey.

《Step 2》
 Hydropath Survey
 *Leak clinic's unique investigation method

Survey to quantify and confirm the deterioration status of areas where water infiltration is possible
A weak current flows from the point that is considered to be the inlet of rainwater and measures the value.
We compare and verify the detected values to narrow down the cause of the leak.

*This is a stand-alone survey using the hydropath, and the cause cannot be identified.
Irradiation water is added to the deterioration area identified by the hydropath survey.

《Step 3》
 Moisture percentage survey

Survey to quantify and confirm the amount of moisture retained in frames, walls, ceilings, floors, etc.
A special moisture meter is used to measure the moisture percentage that is not only on the surface but also in the shallow layer.
From the detection values, we check the wetting range and the direction of flooding.

*This is only a stand-alone investigation using a moisture percentage meter, and the cause cannot be identified.
A hint of the cause may be determined from the moisture percentage on the indoor side.

《Step 4》
 Water Reduction Survey

Survey to confirm water reduction by accumulating survey water in areas where rainwater infiltration is possible
This is a survey to confirm the infiltration of survey water into the frame or wall.
By continuously injecting the investigation water using an IV bottle, we will try to reproduce the leak.
*Watering may be used together.

*The water reduction survey is a very effective survey.
It is important to conduct water reduction surveys in areas with high hydropath values.

《Step 5》
 Fluorescent Fluid Investigation

When it is difficult to confirm leakage with unemployed transparent survey water, investigations using multi-color fluorescent survey solutions
7Use different colored fluorescent investigation solutions to confirm the infiltration route of rainwater.
The survey will also be conducted to keep recorded images.

*The cause of the leak cannot be determined by the fluorescent solution alone.
This is a water reduction survey in which the hydropath value is high, and a fluorescent solution is inserted into the area where the water is reduced to check the fluorescence color.

 Investigation Report

The survey report contains an outline of the survey, discussions, findings, and repair proposals.
We try to explain with words and photos that are easy to understand not only for experts but also for the general public.






《Option 1》
 Rope Access Survey

It is a very effective method in the case of surveys that are not enough to build scaffolding.
Not only will the cost of the survey be reduced, but the burden on the neighbors will be reduced.






《Option 2》
 Drone Survey

High-performance drones can capture high-quality images as well as infrared thermography photography.
What differs from rope access surveys is that it allows for extensive surveys.
By not installing scaffolding, the cost of the survey is reduced.

 Survey Guarantee

We guarantee that you will be re-examined.
A confirmation survey will cost you separately.
The warranty period varies depending on the terms and conditions, such as the location or scope of repairs.
After the repair work (other company), we will conduct a confirmation survey and issue a warranty card if no problems are found.
For details, please check the person in charge or the contents on the warranty card.


*This is only a stand-alone investigation using a moisture percentage meter, and the cause cannot be identified.
The combination of 5 steps is very important!
