vapor barrier against the foundation wall may also contribute to the moisture on the wall
by trapping moisture against the foundation wall. The exterior of the crawl space
foundation did not appear to be damp proofed which may contribute to moisture
penetrating into the crawl space. The moisture has not resulted in structural distress to
the foundation or framing above at this time. However deterioration of the floor system
can be expected if the moisture in the crawl space is not reduced.
It is recommended a visqueen vapor barrier be placed on the crawl space subgrade as
is required by local building code. Sealing of the visqueen at the foundation walls and
I oints would provide a superior vapor barrier. Additionally the -insulation orrthe wails of
the crawl space should be flipped so the backing is facing inward toward the crawl
space. Damp proofing of the foundation wall can be accomplished by applying a
concrete sealer from the inside such as Thoroseal by Thoro Products.
In order to reduce the moisture reaching the crawl space it is recommended the
drainage be improved at the low spot on the north side of the house so a slope
approaching 10% for the first 10 feet away from the foundation is achieved. In addition
it is recommended the grass be removed next to the foundation on the east side for a
distance of at least 5' from the foundation and replaced with landscape rock or
zeriscape requiring no additional water beyond precipitation. All downspout extensions
should be maintained to direct the roof runoff well beyond the buildings foundation.
