The Log Home Neighborhood

An online log home community for log home enthusiasts.

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 site (there are others as well).

I am not a professional....just a guy who builds his own.

Your walls; 

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. 

You might try the B-Dry folks. Zero failures in 50k plus installations since 1955. I used them for sub grade slab issue 8 years ago. I thought I knew enough, only to be educated the hard way.

You gotta address the source. I doubt the sweating walls can be stopped with dry-lock, or a dehumidifier alone, but you can try. Also, get a gutter on the roof with good drainage away on that side of house.

Most basement wall issues are caused by poor placement or slope of footer drains. The 36" footer trench should be dug wider than 24" footing concrete and drains placed at bottom of footers. But that requires framing footers in oversized hole. So shortcut comes with digging 24" footer hole, pouring full of concrete and laying drainage pipe on top of footer. Which leaks in basement under slab with a lot of rain. Go to b-dry site and learn more, and find your local rep.
