My Basement Smells Like Urine - There are numerous approaches to help avoid moisture damage issues at a cellar. The first guideline isn't a dirt basements. Though these are less prevalent in this day in age, it's good to point out that dirt flooring not just hold a huge amount of moisture but can also give off a number of gases. When building a cellar, make sure you've got a floor drain using a trap installed in the bottom point of the ground.
Without a floor drain, any water that is spilled inside can't get out. Sump pumps are often used where flooding due to a high water table might be a problem. Additionally, 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 produced in the house to the outside. Signs of high humidity comprise condensation on walls, pipes or other surfaces as well an overall awareness of moisture in the atmosphere, dampness, and smells. Many times, the humidity will be brought on by exposing the cellar to external air (open windows), using wet laundry hung to dry in the cellar, storing firewood in the cellar, or a dryer vent that exhausts indoors.
In hot, humid weather, keep cellar windows shut. Run the furnace fan continuously to circulate house air. The key to maintaining basement humidity would be to keep them well ventilated and keep additional moisture from the cellar.
