How to Install a Ground Cover
- All crawlspaces, basements, and garages with exposed soil must have a ground cover moisture barrier before insulation is installed.
- The purpose of a ground cover is to keep moisture from moving out of the soil and coming into contact with wood framing and insulation.
- Even if the ground feels dry to the touch, there is probably moisture in it. When the moisture evaporates, the humidity level in the space increases. If the temperature drops below a certain point, the humid air condenses to liquid water on the wood framing. The result could be wood decay.
- Never install a ground cover over standing water.
