Basement Floor Insulation Subfloor - There are numerous ways to help avoid moisture damage issues in a basement. The very first guideline is no dirt basements. Although these are less common in this day in age, it's good to point out that dirt flooring not just hold a huge amount of moisture but also can give off a variety of gases. When constructing a basement, make sure you've got a floor drain using a trap installed in the lowest point of the ground.
With no floor drain, any water that's spilled inside can't escape. If necessary, install a sump pump and ensure that the sump cover is tightly sealed. Sump pumps are often used where flooding because of a high water table may be a problem. In addition, waterproof the outside 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 generated in the house to the outside. Signs of high humidity comprise condensation on windows, pipes or other surfaces as well a general sense of moisture in the atmosphere, dampness, and odors. Many times, the humidity is going to be brought on by exposing the basement to outside air (open windows), using wet laundry hung to dry in the basement, keeping firewood in the basement, and/or a drier vent that exhausts indoors.
In hot, humid weather, maintain basement windows closed. Run the furnace fan continuously to circulate house air. The key to keeping basement humidity low would be to keep them well ventilated and to keep extra moisture out of the basement.
