Many building materials will absorb excess water
vapor and suffer damage, especially when air is
allowed to remain above % relative humidity.
60%
Hygroscopic materials gain and lose moisture
continually in an effort to with the water
content in the surrounding air mass. The more
hygroscopic the material, the faster it will collect
water vapor, and the easier it will suffer
damage.

When water intrusion results in water running through
wall cavities, inspection access holes are used to
ensure that blown-in insulation has not compacted

R-Value , removed
the most effective way to speed the drying process is
to remove as much of the water in a liquid state as
possible during the phase (for example multiple
extractions.) poor extractions will significant slow the
drying process.

Abide by local and regulations when disposing
extracted water. Waste water is best disposed of into
a sanitary sewer.

the primary goal of the initial extraction of the affected
area is to contain further of the water within
