Moisture and Moisture Barriers

Where does moisture come from?
Moisture can come from just about anywhere.  It can come from rain, muggy or humid conditions, leaks, or even watering the garden or lawn.

How can lack of or excess moisture damage my home’s foundation?
Uneven levels of moisture in the soil causes a shift in the soil to expand or contract the foundation, causing the foundation to shift out of place with the soil.

How can I keep moisture from damaging the foundation?
A foundation vapor barrier or a moisture vapor barrier will both help maintain the moisture level under your foundation.  These barriers will prevent any excess moisture from getting under your home’s foundation, but continue to keep in the necessary moisture.
