Drywall or plasterboard is one of the most commonly used materials for walls within a building structure. Moisture related problems on drywall can cause structural damage and potential health problems.
Drywall is a porous material that absorbs moisture easily. Unfortunately, moisture has a negative effect on drywall as its strength and rigidity become compromised. Elevated moisture levels can encourage mold growth which may cause health issues. Thus, there should be as little moisture as possible in drywall.
It is important that any moisture related issues are dealt with as early as possible. Moisture is not always visible on the surface and can be hidden and trapped behind the drywall layer, within the building structure.
By the time moisture or mold is visible, structural damage has already occurred. This can show up as blistering, stains or discolouration.
Thankfully there is a way of detecting this unseen moisture before it becomes noticable and starts deteriorating the building structure. A non-destructive or pinless wall moisture meter, such as the Tramex Moisture Encounter 5, ME5, detects elevated moisture levels within a wall structure without damaging or breaking the surface.
The ME5 moisture meter is the new and improved version of the well-established and trusted Moisture Encounter Plus - MEP, which has been a favourite amongst moisture professionals for many years.
The Tramex pinless moisture meters detect and evaluate moisture conditions within various building materials by non destructively measuring the electrical impedance.
A low frequency electronic signal is transmitted into the material via the electrodes on the base of the Moisture Encounter 5. The strength of this signal varies in proportion to the amount of moisture in the material under test.
The ME5 moisture meter, in drywall scale, determines the strength of the impedance current and converts this to a qualitative moisture content value, displaying it on a clear analog dial.
As the Moisture Encounter 5, ME5, provides qualitative, comparative reading results, it is necessary to first take a moisture reading on a part of the wall that is known to be dry. This reading result can then be used as a reference for ‘acceptably dry’.
This process of pinless moisture testing a drywall structure is not only recommended for locating moisture problems, it can also be used to trace and map the scale of the moisture content issues, without breaking or puncturing the wall surface and structure.
Moisture mapping can be used for:
Detecting the location with elevated moisture content.
Determining the moisture content levels in different areas.
Help locate the origin of the moisture issue, leak tracing or leak seeking.
Monitoring the drying process until acceptable dry levels have been achieved.
Moisture mapping allows for the collection of data from the moment of diagnosis, throughout the mitigation process up until the end of the restoration process.
Tramex Meters has long standing experience in developing accurate moisture detection equipment for moisture related problems within the building structure.
