Bubble Wrap Basement Insulation - There are several approaches to help avoid moisture damage problems at a basement. The first rule of thumb is no dirt basements. Though these are less prevalent in this day in age, it is good to point out that dirt flooring not only hold a huge amount of moisture but also can give off a number of gases. When building a basement, make sure you have a floor drain with a trap installed in the lowest point of the ground.
With no floor drain, any water that is spilled inside can't escape. If necessary, install a sump pump and make sure that the sump cover is tightly sealed. Sump pumps are often used where flood due to a high water table may be a problem. Additionally, waterproof the exterior of the foundation walls and install a perimeter drainage system. An often overlooked problem in basements is moisture that comes out of humidity.
The easiest way to control humidity is to exhaust water vapor generated in the home to the exterior. Indications of high humidity comprise condensation on windows, pipes or other surfaces as well a general sense of moisture from the atmosphere, dampness, and odors. Many times, the humidity is going to be brought on by exposing the basement to outside air (open windows), using wet laundry hung to dry from the basement, storing firewood from the basement, or a drier vent that exhausts inside.
In hot, humid weather, maintain basement windows closed. Run the furnace fan continuously to circulate home air. The key to maintaining basement humidity is to keep them well ventilated and keep additional moisture from the basement.
