My man cave/basement is framed out and there is no heating or cooling in the cabin yet. The basement has always been moist near the end under the most dirt and concrete walls sweat a lot, I know this will not stop until I get some climate control in there, I had seen a mold preventative product being applied to frame work on this site before, it was orange or pink in color, does anyone remember that article or know of similar products ?
This site is a ghost town for advice, I`m guessing if it`s not about a log I`m s.o.l. here !
Its just real bad economy for homes and in particular log and timber.
Middles class has been decimated, and upper spenders are keeping tight...banks are still fixing the housing market to a degree to elevate housing prices on homes they own (read it in Forbes I believe a few months ago). So its been pretty tough to get conversation on a lot of these sites.
Have you searched http://www.greenbuildingadvisor.com/ site (there are others as well).
I am not a professional....just a guy who builds his own.
I don't know why they sweat?
I don't have that problem, but I live in Maine, so maybe different climate has different problems.
Did they use damp-proofing or waterproofing on the outside?
Is there some form of insulation on the outside below ground to help buffer temp. changes between inside temp and outside soil temp?
Good perimeter drains?
Back fill with water retaining soil or sand / gravel?
I know some people up my way are now installing heat pump hot water heaters, which will dehumidfy your basement and generate hot water at the same time. They have a slow recovery rate, but save a lot on hot water costs and dehumidify for free (basically saving you $1 a day to run a dehumidfier). Some states are offering rebates on top of the federal tax credit.
Not sure of what state you are and what temperature parameters you face. The temperature difference between the below grade surfaces and the air is creating condensation. Although I cannot speak to additives for wood installed already, the lumber is absorbing the moist and a dehumidifier could be beneficial.
