Moisture On Vapor Barrier
This moisture barrier was placed on top of the soil
underneath the house flooring in the crawlspace area. The vapor barrier
is made from plastic and appears to be wrinkled and wasn't installed
very good. The crawlspace soil area or flooring should have been
smoothed down and flattened, and then the plastic vapor barrier could
have been installed properly.
If you look towards the center of the wet spot on top of the plastic,
you will notice that there is an orange and brown stain forming. This
tells me that there's metal rusting somewhere and water dripping from
it, on to the plastic. There's a good chance that the water on top of
the plastic vapor barrier is coming from a damaged or leaking water
pipe.
There shouldn't be any moisture on top of the plastic that is separating
your crawlspace area from the soil underneath it. These plastic vapor
barriers are designed to keep moisture in the soil and out of your
crawlspace area.
Homeowner Repair Tip: It's not a bad idea to install a vapor barrier in
between the damp soil and the floor of your home. However, it should
slope towards a drain or sump pump. This would provide you with a way to
get rid of excess of moisture as it accumulates on top of the plastic.
