Vapor Barrier Mt. Pleasant SC

A vapor barrier can be installed in your crawlspace to help control moisture conditions. East Cooper residents often find their hardwood floors may be cupped or wavy when the humidity levels increase in our area. Basically there are three main factors that contribute to an increase in moisture in your crawlspace.

1. Evaporation from the earth.

2. HVAC lines may sweat causing condensation in the crawlspace.

3. Mother Nature. Humid air moving into the crawlspace area during times of high humidity.

Sometimes these three factors are all working together to create a perfect “moisture storm” in your crawlspace. Installing a vapor barrier will control evaporation from the earth. Usually, a six millimeter vapor barrier does the job and will hold up for 10-15 years.

According to the Rules and Regulations of the South Carolina Pesticide Control Act, in Section 27-1085 titled South Carolina Standards for the Prevention or Control of Wood Destroying Organisms, Section J Paragraph (2) states “If moisture condensation of soil moisture is occurring on the substructure wood, it can be prevented by installing a vapor barrier. An adequate barrier can be made by covering the soil under the structure with polyethylene sheets. Normally not more than 70% to 80% of the crawlspace soil should be covered.”

Some extreme cases of high moisture readings in the wooden substructure of your home may require the installation of a dehumidifier in the crawlspace. East Cooper Termite and Pest Solutions can evaluate the moisture conditions in your crawlspace and recommend the best remedy to control unwanted moisture.
