Why Flooring Installers Need To Measure Moisture Content In Wooden Subflooring
#1: Take Moisture Measurements Earlier Than, During, And After Installation
A crawl area is an space under a wooden subfloor or the ground joists. These areas account for numerous issues when associated with hardwood floors. Proper air flow have to be allotted and the area be protected with thick plastic film on what is normally topsoil. Covering is one requirement, maintaining moisture from collecting or forming in puddles on top is one other.

Insulating all but the ideas of these pins prevents a false moisture content material studying and supplies a extra correct reading at the depth where the information of the pins are uncovered. Yes, it's possible to have a moisture content studying of ninety nine.9%. It can be potential to have moisture content readings over one hundred%. This means the load of the water exceeds the load of the wood by itself.
What is a bad moisture reading?
When using the wood scale on a pin-type moisture meter, the %MC reading can range from 5% to 40% in moisture content. Generally, the low end of this reading will fall into the 5 to 12% range, the moderate range will be 15 to 17%, and the high or saturated range will read above 17%.
However, the company who maintains the dehumidifier mentioned he tested a few of the joist which he said solely registered 10 on his system. I don’t know what to consider besides the company who put in the vapor and dehumidifier stated the vapor barrier needs to be modified out because of all of the sewage and drainage stains after the plumbing is mounted. One of his personal service guys stated foundation caps needed to get replaced. The plumbing was improperly installed with the wrong cement to suit the pipes and will have been leaking from wherever between 5-29 years whereas absorbing into the bottom.

This method of measurement is taken into account invasive as a result of it requires puncturing the material to acquire a outcome. However, pin moisture meters are the only type that can assist identify the precise location of moisture.

They may have the ability to offer you correct moisture testing procedures and species corrections for their product. If not, contact the meter manufacturer for correct species correction settings. Moisture meter manufacturers use calibration curves to determine corrections for testing that species. Most meter producers have calibration curves for a lot of the species and subspecies used within the flooring industry and are usually fairly accurate to inside +/-1 to 2 %.
Step 2: Set Your Meter
Be positive to acclimate the wooden to desired EMC of the inside setting before you use it. The ASTM D4442 normal determines the accuracy of wooden moisture meters. This technique uses the oven-dry methodology after which compares the results to these obtained utilizing a moisture meter. These various humidity ranges of the surrounding air cause wood to not only gain or lose water moisture however to increase or shrink as properly. As the humidity will increase, the MC increases, inflicting the wooden to broaden. As the humidity decreases, the MC decreases, inflicting the wooden to shrink. When the wood neither gains nor loses moisture, we are saying that the wooden has reached its equilibrium moisture content .
Similarly, you need to use a moisture meter to make sure that your house is moisture-free, or ensure the quality of material during DIY tasks. A moisture meter can help you decide when you have too much moisture or need a humidifier.
