Insulating A Basement Wall With Rigid Foam - There are several approaches to help prevent moisture damage problems in a cellar. The first guideline isn't a dirt basements. Although these are less common in this day in age, it's good to point out this dirt flooring not only hold a huge amount of moisture but can also give off a number of gases. When constructing a cellar, make sure you have a floor drain with a trap installed at the lowest point of the ground.
With no floor drain, any water that is spilled inside can't get out. If necessary, install a sump pump and ensure that the sump cover is tightly sealed. Sump pumps are usually used where flooding due to a high water table may be a issue. Additionally, waterproof the exterior of the base walls and put in a perimeter drainage system. An often overlooked problem in bathrooms is moisture that comes from humidity.
The easiest way to control humidity would be to exhaust water vapor produced in the house to the exterior. Indications of high humidity include condensation on walls, pipes or other surfaces as well a general awareness of moisture from the atmosphere, dampness, and smells. Often, the humidity is going to be brought on by exposing the cellar to outside air (open windows), using wet laundry hung to dry from the cellar, keeping firewood from the cellar, and/or a drier vent that exhausts inside.
In warm, humid weather, maintain cellar windows closed. Run the furnace fan continuously to circulate house air. The key to maintaining basement humidity would be to keep them well ventilated and to keep additional moisture out of the cellar.
