Re: Slab on Grade and the Green Code

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I agree. It was a good discussion, though my initial post was intended to 
resolve a conflict between a code requirement and a soils engineer who 
thought it was a bad idea and who insisted he wanted the sand layer to 
protect the plastic sheet. I wish I can disagree with a structural code 
requirement, then put a statement on the plan that I take full 
responsibility, if my approach fails ;)

I guess somebody needs to stir the pot every once in a while to get all 
those dormant great minds to contribute to this list with useful 
information and interesting discussions.

Hello Chuck & Board,

Thank you for all of your responses.  I realize that Oshin started
this thread, but I appreciate all of the great input and links to
articles on this subject.  I have learned much.

My approach was from information gleaned from old concrete
installers, who preferred the sand.  When I asked about why it's
there, they tried to answer me with what must have made sense
to them.  I have learned today, that there is a better approach to
determining when and where to use a vapor barrier.

Thank you,
