Crawlspace Vapor Barrier
I’m working on sealing up my crawlspace, as I am starting to have issues with humidity, musty smells, etc. A few years ago, I put two coats of dryloc masonry sealer on the brick, now I’m putting 6 mil plastic to cover the dirt floor. Im having issues attaching the plastic to the wall. Ive tried construction adhesive—which sticks very well to the brick but doesnt hold the plastic. Im not sure what else to try...maybe double sided tape?

Tape, mastic, other options as well.
Have you done work outside the structure to divert water away in the first place as well?

Mastic should work. Or tack a cleat onto the sill plate or floor joists to hold it in place until it has stuck to the mastic.

I might try the mastic next. Im really not sure why the construction adhesive didnt work, i made sure the plastic was clean first. I read another thing that said acoustic caulk, but its like $7 per tube. Id like to find something that works without spending a million dollars lol.
