I have a 16′ X 28′ timber frame camp built in Maine with a concrete perimeter foundation to below frost with a earth floored crawl space. The building has perimeter drainage on the outside and
around the interior perimeter of the foundation. I have insulated the floor with 6″ of fiberglass and
have put poly on the surface of the earth floor. I am getting water on the surface of the poly that
appears to be condensation. What can I do, if anything to eliminate this problem? At present the
joists, and sill appear to be dry and the moisture is only on the poly covered floor.

Margaret,
The water on the surface of the poly could be from a dozen sources and by itself is not cause for worry. You may want to check for leaks.
If the rest of your basement structure is dry, a little water on the poly will not hurt anything. Just monitor it at different times and unless there's an increase in the moisture level, do enjoy your camp.
