Leveling Basement Floor Over Asbestos Tile - There are numerous ways to help avoid moisture damage problems at a basement. The very first guideline isn't a dirt basements. Though these are less common in this day in age, it is a good idea to point out that dirt flooring not just hold a huge amount of moisture but can also give off a number of gases. When constructing a basement, make sure you have a floor drain with a trap installed at the bottom point of the floor.
With no floor drain, any water that's spilled inside cannot get out. Sump pumps are often used where flood due to a high water table might be a issue. In addition, waterproof the outside of the base walls and put in a perimeter drainage system. An often overlooked problem in basements is moisture that comes from humidity.
The easiest way to control humidity would be to exhaust water vapor produced in the home to the outside. Indications of high humidity include condensation on windows, pipes or other surfaces as well an overall sense of moisture in the air, dampness, and smells. Many times, the humidity is going to be brought on by exposing the basement to outside air (open windows), having wet laundry hung to dry in the basement, keeping firewood in the basement, or a drier vent that exhausts indoors.
In summer, use a portable dehumidifier or air conditioning to reduce humidity. In hot, humid weather, maintain basement windows shut. Run the furnace fan continuously to circulate home air. The key to keeping basement humidity low would be to keep them well ventilated and keep additional moisture out of the basement.
