Reinforced Concrete Basement Walls - There are several approaches to help avoid moisture damage issues in a cellar. The first guideline isn't a dirt basements. Although these are less prevalent in this day in age, it is a good idea to point out that dirt flooring not just hold a large amount of moisture but can also give off a number of gases. When building a cellar, make sure you have a floor drain using a trap installed in the lowest point of the floor.
Without a floor drain, any water that's spilled inside cannot escape. Sump pumps are usually used where flood due to a high water table may be a problem. In addition, waterproof the outside of the foundation 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 generated in the home to the outside. Signs of high humidity include condensation on walls, pipes or other surfaces as well a general awareness of moisture from the air, dampness, and odors. Many times, the humidity will be brought on by exposing the cellar to external air (open windows), using wet laundry hung to dry from the cellar, keeping firewood from the cellar, or a drier vent that exhausts inside.
In summer, use a portable dehumidifier or air conditioning to decrease humidity. In warm, humid weather, maintain cellar windows closed. Run the furnace fan continuously to circulate home air. The real key to keeping basement humidity low would be to keep them well ventilated and keep additional moisture out of the cellar.
