Sealer For Basement Walls And Floors - There are several ways to help prevent moisture damage problems at a cellar. The very first rule of thumb is no dirt basements. Although these are somewhat less common in this day in age, it's good to point out that dirt floors not only hold a huge amount of moisture but also can give off a number of gases. When constructing a cellar, make certain that you have 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 usually used where flood due to a high water table might be a issue. Additionally, waterproof the exterior of the base walls and put in a perimeter drainage system. An often overlooked problem in basements is moisture that comes out of humidity.
The easiest way to control humidity would be to exhaust water vapor produced in the house to the exterior. Indications of high humidity include condensation on walls, pipes or other surfaces as well a general sense of moisture in the air, dampness, and smells. Many times, the humidity is going to be caused by exposing the cellar to outside 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, keep cellar windows closed. The real key to keeping basement humidity low would be to keep them well ventilated and keep extra moisture from the cellar.
