Crawl space renovation – floor choice?
I am currently insulating my crawlspace, and then will redo the floor — currently it is just earth.
(I guess we have a CS in the first place, because the house is split levels, with a partial basement, and is built on a slope…). So there is no (apparent) groundwater around…
Still, the even though the CS does not appear to be *very* damp, it IS damp-ish, and I don’t want said damp, nor the unpleasant musty smell that goes with it !
If I understood right, there seem to be two recommended methods for floor treatment – either encapsulation using a vapor barrier, or pouring of a concrete slab.
I only have 33 inches of free height at best, and given the uneven nature of the floor (ups and downs, trench, slopes…), I wanted to make the job as easy as possible for myself…
So I don’t see me mixing loads of concrete down there, and I cannot barrow concrete in, as no access, and I cannot afford to have a concrete pumper on site.
Also, I cannot quite see a polythene vapour barrier looking OK, given the contours. The CS is 40 foot long by 13 foot wide. Access door is 30 inches square.
So I am wondering if I can take a third route, namely, “grossly” leveling the floor (removing rubble, rocks, a certain amount of earth), then mixing in some bags of lime, and adding water, to stabilize the earth and “lock in” the fusty smell.
Would this make the CS any healther ?
Would appreciate your feedback
