Measurements of moisture in building partitions

Moistened building partitions (external and internal walls and roofing) are a very serious problem not only due to the decrease in the quality of the indoor environment but above all to a significant reduction in their thermal insulation properties, which in turn can lead to a significant increase in costs related to heating energy demand .

Non-destructive measurements of humidity of building partitions offered by Roof Consulting are a kind of complement to the offered non-destructive leak detection systems and allow for a slightly broader interpretation of the phenomena of building physics occurring inside building partitions.

Thanks to microwave humidity measurements, it is possible to determine the moisture content of building partitions inside their structure and on their surface.

On the basis of properly made and interpreted measurements of humidity on the surface of the partition and inside it, it is possible, among others:

• location of the area of ​​potential leaks and leaks causing moisture of partitions (in this place it should be mentioned that the moisture of partitions, e.g. walls, can be caused not only by leaks caused by leaks in roof waterproofing, but also by e.g. leaks in internal water installations, etc.)
• determining the degree and distribution of moisture in building partitions due to excessive moisture condensation caused by the occurrence of a given location, e.g. a thermal bridge (the thermal imaging cameras described in the previous study are used for the possible location of thermal bridges, however, humidity measurement devices determine the distribution of moisture in the partition and moisture content) or insufficient or improper thermal insulation;
• determining the distribution of cracks conducting penetrating ground water in diaphragm walls constituting external partitions, e.g. underground garages (these walls are usually covered from the inside with a layer of leveling concrete, which makes it impossible to determine the exact distribution of cracks without first forging this concrete);
• determining the degree and distribution of moisture of building partitions due to the possibility of water capillary rising through inadequately insulated wall foundations

Our measuring devices allow you to perform measurements of the level of humidity both on the surface of the tested partition (at a depth of max. 3 cm) as well as inside it (to a depth of about 30 cm).

Full computerization of devices enables the collection of a significant number of measurement readings at various characteristic points of the tested partition, and then their clear presentation allowing for proper interpretation of the cause of excessive moisture.

The technology for measuring humidity is completely non-destructive (it only involves applying a special measuring head to the tested partition), and therefore does not require tedious, sometimes difficult to perform material openings (and subsequent long-term laboratory tests) and also allows testing of materials constituting the load-bearing structure (e.g. .: reinforced concrete), which sometimes can not be violated.
