Question
Hello Bruce

I live in sw mn, and am thinking of building a new home.  What if any would be the pros vs. Cons of doing a wood basement over poured concrete.  I'm thinking wood, because of the time frame, the carpentry can start working on it right away, and might be cheaper than concrete.
Your thoughts,
Thanks,
Nate

Answer
Hi Nathan, I have reviewed wood basements over the years as compared to concrete and to be honest I have nothing positive to say about the wood.  Wood is not permanent no matter how it is treated.  Wood walls don't have the sheer capabilities of withstanding hydrostatic pressure as far as I'm concerned.  A good form contractor can dig, form and pour a concrete basement foundation in a week so time isn't that big of a factor either.  Concrete, after it is poured can be waterproofed with a good rubber mastic brushed or rolled on.  Wood, in order to be waterproofed has to have an impervious barrier of felt or other material applied to it and then you hope to heck that it won't leak.  Both foundations need drains around them to divert water away from the walls.  I don't see how a wood foundation can be cheaper than concrete by the time the walls are waterproofed and insulated.  So, my take on it is "go concrete"!  I hope this information helps feel free to write again regarding this or other matters, sincerely bruce e johnson..bejohnsonconsulting.com
