Basement Floor Insulation Options - There are numerous approaches to help prevent moisture damage problems in a basement. The very first rule of thumb isn't a dirt basements. Although these are somewhat less common in this day in age, it is a good idea to point out this dirt floors 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 at the lowest point of the ground.
Without a floor drain, any water that's spilled inside cannot get out. If necessary, install a sump pump and make sure that the sump cover is tightly sealed. Sump pumps are often used where flood because of a high water table may be a issue. In addition, waterproof the outside of the base walls and install a perimeter drainage system. A frequently overlooked problem in bathrooms is moisture that comes from humidity.
The simplest way to control humidity would be to exhaust water vapor generated in the home to the outside. Signs of high humidity include condensation on walls, pipes or other surfaces as well an overall awareness of moisture from the air, dampness, and odors. Many times, the humidity is going to be caused by exposing the basement to outside air (open windows), using wet laundry hung to dry from the basement, keeping firewood from the basement, and/or a dryer vent that exhausts inside.
In hot, humid weather, keep basement windows shut. Run the furnace fan continuously to circulate home air. The real key to maintaining basement humidity would be to keep them well ventilated and keep additional moisture from the basement.
