Permanent Wood Foundation Basement - There are several approaches to help prevent moisture damage issues at a cellar. The very first guideline is no dirt basements. Although these are less prevalent in this day in age, it's a good idea to point out that dirt flooring not only hold a large amount of moisture but can also give off a variety of gases. When constructing a cellar, make certain that you've got a floor drain with a trap installed at the bottom point of the floor.
Without a floor drain, any water that is spilled inside can't escape. If needed, install a sump pump and make sure that the sump cover is tightly sealed. Sump pumps are usually used where flooding due to a high water table may be a problem. In addition, waterproof the outside of the foundation walls and install a perimeter drainage system. An often overlooked problem in basements is moisture that comes out of humidity.
The simplest way to control humidity is to exhaust water vapor generated in the home to the outside. Signs of high humidity comprise condensation on walls, pipes or other surfaces as well an overall awareness of moisture in the atmosphere, dampness, and smells. Many times, the humidity will be brought on by exposing the cellar to outside air (open windows), using wet laundry hung to dry in the cellar, storing firewood in the cellar, and/or a drier vent that exhausts inside.
In summer, use a portable dehumidifier or air conditioning to decrease humidity. In warm, humid weather, keep cellar windows shut. Run the furnace fan continuously to circulate home air. The real key to keeping basement humidity low is to keep them well ventilated and to keep extra moisture out of the cellar.
