Concrete Basement Construction Details - There are several ways to help avoid moisture damage issues at a basement. The first guideline is no dirt basements. Though these are somewhat less prevalent in this day in age, it's good to point out this dirt floors not just hold a huge amount of moisture but can also give off a variety of gases. When building a basement, make certain that you've got a floor drain using a trap installed at the bottom point of the floor.
Without a floor drain, any water that's spilled inside can't escape. Sump pumps are often used where flooding because of a high water table may be a issue. In addition, waterproof the exterior of the foundation walls and install a perimeter drainage system. A frequently overlooked problem in basements is moisture that comes from humidity.
The simplest way to control humidity is to exhaust water vapor generated in the house to the exterior. Signs of high humidity include condensation on walls, pipes or other surfaces as well a general sense of moisture from the air, dampness, and odors. Often, the humidity will be brought on by exposing the basement to outside air (open windows), having wet laundry hung to dry from the basement, storing firewood from the basement, or a dryer vent that exhausts indoors.
To reduce humidity, there are several things that a homeowner can do: install energy-efficient windows, insulate walls and cold water pipes, prefinished flooring if possible, run dryer vents to exhaust directly out and don't dry laundry or firewood in your basement. In warm, humid weather, maintain basement windows shut. Run the furnace fan continuously to circulate house air. The real key to keeping basement humidity low is to keep them well ventilated and to keep extra moisture from the basement.
