Removing Moisture from Materials

1/10/2023 (Permalink)

When our crew approaches a water job, we evaluate many different variables. All of which are very important, but there are two variables that we look at the most: type of material and the degree of wetness. This means that we will evaluate each material's permeability, the ability for water to pass through the material, dampness, the moisture movement. The liquids will be presented in one of these forms.

Surface Water

Like the name, you can find this type of moisture on the material's surface. It is a visible liquid and can evaporate. When mitigating this type of moisture, you must remove the moisture using mechanical extraction. The next component needed to be addressed: airflow, which helps control temperature and humidity, which helps evaporate any remaining moisture.

Free Water

Unlike surface water, the name of this absorption doesn't give you many clues on how to find it in a material. Before the moisture can form a chemical bond to the material, free water happens. You can find this type of moisture in cavities, open pores, and other air spaces within the material. When mitigating this form of moisture, you will want to use lower humidities and warmer temperatures. By maintaining these factors, you ensure that the moisture is going to evaporate.  

Bound Water

More work is needed to fully mitigate this type of moisture material as this form is when the moisture has made chemical bonds. You will have to release it to get the moisture out of the material when this happens. Unlike the other categories, controlling the airflow won't help remove the chemical bonds. The moisture will dry fastest when it is warmed. The essential factor to keep in mind is maintaining the surrounding humidity. Keep in mind that this type will take the longest to dry out of all categories.

This is why you should hire our team of professionals here at SERVPRO because we know what to look for. We evaluate each material to create a precious course of action to provide results and restore to the preloss condition.
