Crawlspace Vapor Barrier
In a recently flooded crawlspace,I have a concrete rat slab(approx 2 1/2" thick).However the slab has no vapor barrier under it.The slab itself is below outside grade about 18".I want to control the moisture level in this crawlspace.The crawlspace,doesn't get standing water in it,nor does the groundwater seem to exert any problems to it.The flood was a freak occurrence.
The slab is rough finished and not very smooth.I wouldn't trust poly over it,with any activity at all.The subfloor will be removed soon,completely exposing the crawlspace.I want to take care of things then.I suppose I could remove the slab,put poly down and pour a new slab.Or I could put a very heavy poly over the existing and pour a new slab.Or I could make an attempt to seal the existing slab some how.Any suggestions?
