Basement Moisture Problems
Nearly every home has a basement moisture problems, assuming there is
a basement in the home. The basic reason is that the basement, or
part of it, is below ground level. A basement in modern homes is an
extension of the living space in addition to an area for storage,
and a place for the utilities such as; furnace, boiler, hot water
heater, and water tank. There are several different styles of
basements from day light (essentially a walkout), to lookouts where
there are windows in the basement that permit a view outside.
For clarification of terms
a cellar is not a basement but is often
referred to as such. Although a cellar is a type of basement it is
primarily used for the storage of food and drink
(wine) for use throughout the
year. A cellar by design is intended to remain at a constant cool (not
freezing) temperature all year round, approximately 60 degrees. They are
more common in older houses than in modern houses and are not intended
for living space although they serve as an excellent shelter from
tornadoes in some parts of the country. Moisture in a cellar is not
considered a problem because they are not intend to be used as living
space.
Because basements are in part or in whole below
ground there are several things that cause moisture to accumulate.
First the difference in the temperature between the earth on the
outside wall (foundation) and below the concrete floor. In modern
construction basement sealing with vapor barriers are placed beneath the the concrete
floor and the foundation is sprayed with a moisture sealant in an
attempt to keep out the moisture. Although these methods are
effective they do not keep all the moisture at bay. In addition, a
lot of the moisture comes from the cold water tank and water pipe
sweating due to the difference in temperature of the basement and
the water.
It isn’t common for basements to have visible
water leaks in modern home construction where crushed stone is used
below the concrete floor and foundation drains are installed to
carry water away from the building. Prior to installing foundation
drainage it was quite common for water seepage into the basement
following a heavy rain, sometime a great deal of water. Sump pumps
were the solution to get rid of the water however the basement moisture
problems remain. Installing gutters to take rain water away from
the building also helps remedy the problem. Painting the inside foundation walls with a
moisture inhibitor paint helps but cannot solve the problem of the
temperature difference between the outside and the inside of the
basement. The practical solution is to install a dehumidifier as a DIY
project. In a
typical basement as dehumidifier will abstract five or more gallons of
moisture a day during the warm summer season and significantly less
during the drier winter season. If you have a wet basement from moisture problems I recommend
the following:
Basements with excessive moisture are not a healthy living space environment and should be resolved as soon as possible.
