Measuring wall moisture - facts and figures

There is a not inconsiderable causality between the development of mold and damp masonry. So with the exact Root cause analysis However, no mistakes are made, the aim here is to explain how moisture in the walls can be measured with simple aids. After all, it is essential to first know exactly what the cause of damp walls is so that specific measures can be taken. And that is part of that Wall moisture measurement first of all. This not only saves costs, it also saves nerves.

Because only with the right key figures and the corresponding knowledge can targeted action be taken against the formation of mold or, for example, wall nitrate. Interior insulation with silicate panels, for example, can already be an effective measure to both prevent and combat moisture damage. Whether this is necessary, however, must be made dependent on the moisture content of the masonry.

How do you know if the wall is damp?

Often, moisture can be detected in the walls as soon as you enter a room. Factors can be:

  • Visible staining
  • Mold growth
  • Musty smell
  • Damaged plaster (paint, wallpaper, etc. are peeling off)
  • Condensate deposits


But if there is an unpleasant, musty smell in the air when you enter a room or if there are moisture stains on the wall, then it is usually almost too late. Here is the one Contact the specialist urgently recommended, as the damage is usually barely visible to the naked eye. With damp walls and water damage, beams can warp, frost damage and corrosion such as mold can result. If, in extreme cases, it is necessary to dry the walls, that's a professional thing. For moisture in the masonry it canvarious causes and the removal is sometimes not that easy. For example, the water can collect due to structural conditions or there are gaps in the insulation. Particularly in areas such as basements, a certain basic moisture level often rises from the ground and makes use of even the smallest structural weakness in the seal. If moisture penetrates the foundation from outside, it is essential to dry the building immediately to prevent mold. It therefore pays to take precautions early in order to prevent heat loss in the house and to proactively avoid moisture.

If the damage has already occurred, no attempt should be made to repair sporadically here and there and to dry wet walls with a hair dryer or radiant heater. Complete and professional wall drainage is of fundamental importance in order to sustainably eliminate water damage.

How is the moisture in the wall measured?

To be the main cause of Detect mold and other problems early onan appropriate moisture meter is required. Such devices do not necessarily have to be expensive to display a usable result. The use of a wood moisture meter, for example, is also suitable. This is usually used to measure the moisture of the firewood. With a price range of 20 to 100 euros, such a device is easily affordable and worthwhile in the long term, especially in terms of prevention. Since the device supports theelectrical resistance you can also use it to measure wall moisture.

An exploration of this kind helps to identify concrete need for action at an early stage and to plan measures. A possible source can also be identified locally, for example if it is a defective line. Such damage can be quickly identified by gradually probing and measuring the moisture in the wall. For more precise information, a selective Drill sample be made. Material is removed from the wall, weighed and then dried. A new measurement is then carried out to check any difference. This method is complex, however, since several holes have to be drilled in different places to ensure a certain representative quality.

What is the normal humidity level?

Will give you values between 0.2 to 0.3 percent Moisture displayed, the values ​​are harmless. You should be careful when the device becomes damp0.4 to 0.9 percent indicates. In this case, appropriate countermeasures should be planned with a specialist. But what is important is scalability. During the measurement, a certain basic humidity must be analyzed in the context of room humidity. Since this is usually also measured, it can be assumed that a displayed total humidity of less than 80% is a good sign.
