Moisture measurement helps you to find out if there is too much moisture in your structures and to determine the moisture content of the indoor air. The measurement will inform you about the necessary corrective measures.

Moisture measurement and remedial measures ensure that structures and indoor air quality do not deteriorate over time due to latent moisture.
Several methods are used to measure the moisture content of structures and indoor air. As a non-destructive method, a surface moisture meter is often used first to determine the moisture differences between materials. The surface moisture meter is an excellent tool for moisture mapping, especially for locating latent damage that is difficult to detect organoleptically. Due to the unreliability of the surface moisture meter, the accurate determination of the moisture content of structures has to be carried out by other methods of moisture measurement, such as drill hole measurement and sample palpimetry for concrete structures.
There are many legitimate reasons for carrying out a moisture survey. For example, when selling or buying a home it is also in the interest of both parties to determine and measure the actual damp-proof condition of the property to be sold. Moisture problems are commonly found in basements, ceilings, insulation spaces, frame structures and spaces where water is handled such as washrooms, toilets, saunas and utility rooms. A thorough damp survey by a professional will identify the areas of the property affected by damp and their actual condition.
A written and electronic report of the moisture survey will be produced, showing the results of the survey, the interpretation and the proposed remedial measures, including a possible drying plan for areas with moisture. Based on the proposed measures in the dampness survey report, remedial works can be carried out in a cost-effective manner using correct and efficient methods.
We are often asked if we can do a simple bathroom humidity measurement. The answer is, yes. We do this regularly in Uusimaa, especially in Helsinki, Espoo and Vantaa.
Temperature is also the most important factor in drying out structures. In mechanical drying, technical equipment and compartmentalisation can control the prevailing conditions to achieve the most efficient drying and minimise damage quickly. The drying plan in the moisture survey report defines the optimal drying solution for each site.
Moisture damage under the plastic mat can be detected by a slit measurement. A slit measurement can be used to measure the amount of moisture trapped under the plastic mat, between the structures. It is difficult to detect the moisture condition under the plastic carpet by sensory means. In this case, slit measurement is the best solution.
In a borehole measurement, a hole is drilled in the material to be measured to a specified depth and the moisture is allowed to equilibrate with the surrounding material for a certain time (approx. 3 days) before the measurement. The borehole measurement can be carried out in a temperature range of +15-25°C. If the temperature of the concrete structure is such that a borehole measurement cannot be carried out, the measurement must be carried out, e.g. by the split-sample method.
Fire assay is the most reliable, accurate and fastest method for determining the moisture content of a concrete structure. Due to its accuracy and reliability, it is the method of choice when good measurement accuracy is to be maximised. The sample return measurement can be taken from the structure over a temperature range of -20°C to +80°C. From the time of sampling, results are usually available after a 6-12 hour sample equilibration period.
Moisture can also penetrate trees, causing decay. Moisture measurements of wooden building materials are taken with a spike meter. The moisture measurement with a spike meter is based on measuring the electrical conductivity between two metal electrodes pressed into the wood. As a more homogeneous material than concrete, wood is relatively reliable.

In order to manage moisture in buildings, it is important to know the moisture performance of the building. Moisture damage to building materials will occur if the structure is exposed to too much moisture for too long.
The challenging seasons in Finland are very variable, which can cause moisture to enter structures, even if there is no specific damage to the building. Knowledge of the basics of building physics is essential at all stages of a building's life cycle (design, construction, renovation, maintenance, use).
Moisture measurements are also needed during the construction phase to monitor the drying of building materials, for baseline measurements and documentation, and for pavement constructability measurements. In the investigation of water damage and suspected water damage, professional moisture measurements are essential for identifying the damage and the need for repair, and for planning water damage drying and damage repair.Moisture measurements are useful in both small dwellings and large building complexes. If one area of a building becomes symptomatic as a result of water damage, the whole building will suffer.
The most important thing is to act quickly. But don't panic. Prevent further damage if possible.
In the event of a pipe leak, find out where to locate the water stopcock. The tap is usually found in the same place as the water meter.
If the dishwasher is leaking, turn off the dishwasher and turn off the tap.
If the water damage is minor and you have managed to dry the loose water yourself, a damp survey is carried out 3 days after the water damage.
Our on-call JVT department (JVT=juvenile damage prevention) is quickly on the spot and further damage can be minimised with the right operations and equipment.

A clear written and electronic report of the moisture measurements we carry out is always produced. The report explains the moisture content and structural condition of the materials tested, any potential moisture damage and the recommended measures to remedy any problems. The report is done so that, if possible, the results are obtained on the same site visit (results available immediately, no drill hole or sample split methods). With modern equipment and a report prepared by our certified structural moisture surveyor, planning and budgeting for the cost of restoration work is easier.
