Insulated Basement Floor Systems - There are numerous approaches to help prevent moisture damage problems at a cellar. The first rule of thumb isn't a dirt basements. Although these are somewhat less common in this day in age, it's a good idea to point out this dirt floors not just hold a large amount of moisture but can also give off a variety of gases. When constructing a cellar, make sure you have a floor drain with a trap installed at the bottom point of the floor.
Without a floor drain, any water that is spilled inside cannot escape. Sump pumps are usually used where flood because of a high water table might be a issue. Additionally, 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 simplest way to control humidity is to exhaust water vapor generated in the house 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 will be caused by exposing the cellar to external air (open windows), using wet laundry hung to dry in the cellar, storing firewood in the cellar, and/or a drier vent that exhausts indoors.
In hot, humid weather, maintain cellar windows closed. The key to keeping basement humidity is to keep them well ventilated and to keep additional moisture out of the cellar.
