Water Coming Up From Basement Floor Drain - There are numerous approaches to help avoid moisture damage issues at a basement. The first rule of thumb isn't a dirt basements. Though these are less common in this day in age, it is a good idea to point out this dirt flooring not just hold a huge amount of moisture but can also give off a number of gases. When building a basement, make sure 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 cannot escape. If necessary, install a sump pump and ensure that the sump cover is tightly sealed. Sump pumps are usually used where flood due to a high water table might be a problem. In addition, waterproof the outside of the base walls and install a perimeter drainage system. An often overlooked problem in bathrooms is moisture that comes out of humidity.
The simplest way to control humidity is to exhaust water vapor generated in the house to the outside. Signs of high humidity include condensation on windows, pipes or other surfaces as well an overall sense of moisture in the atmosphere, dampness, and odors. Often, the humidity is going to be brought on by exposing the basement to external air (open windows), using wet laundry hung to dry in the basement, storing firewood in the basement, and/or a dryer vent that exhausts indoors.
In warm, humid weather, keep basement windows closed. Run the furnace fan continuously to circulate house air. The real key to maintaining basement humidity low is to keep them well ventilated and keep extra moisture from the basement.
