Facts - Internal Moisture

Internal
Moisture
Internal moisture, usually in the form of humidity,
can cause condensation on the surface of the walls as
well as condensation inside the wall itself. The goal
when considering moisture protection details is to avoid
allowing moisture, either from external or internal
sources, to damage the building or make the building
uncomfortable.

Cool Facts
- Where the humidity is high or where the concrete
is exposed to frequent precipitation, the internal
moisture content will remain high. Protective systems
applied to moisture-laden structures can fail prematurely
if moisture movement within and through the structure
is not considered
- Moist walls can allow mold to grow, cause surface
discoloration and cause damage to plaster and wall
finishes
- Certain spray-on waterproofing coatings may trap
moisture within your home
- 95% of the moisture entering a building enters through
air infiltration. 5% of the moisture enters by diffusion
through building materials
- Approximately 1 cup of water can move through a
10" X 10" section of painted wall per year
by diffusion, but as much as 5 gallons can get through
a ¼” hole in your foundation per minute.
(Better get SUPERSEAL)
- Mopping the floor in a 150-square-foot kitchen can
release the equivalent of 4.5 pints of water into
the air, a shower or bath about .5 pint. Also, a family
of 4 gives off about .5 of a pint of water per hour
just breathing

The SUPERSEAL Solution Moisture
is created within your home from several sources, cooling
systems, icemakers etc. Some waterproofing methods can
trap moisture in the home not letting the foundation
to breathe. Since the air gap membrane is closer to
the soil, it becomes the coldest surface causing the
moisture to attract to it instead of the inside of your
home. When the moisture hits the air gap, it percolates
down to the footing drain for removal. The membrane
may continually draw moisture from within your house
outwards year after year. SUPERSEAL Dimpled Membrane
will help decrease the level of moisture inside your
home.
