It works great to attach visqueen sheeting through butyl tape to concrete foundations in the crawl space. We put this in high traffic areas where the tape might slip, and along the wall at about 2'-0" on center. Just use a 1/4" hammer drill bit, drill about an 1" (25mm) and pop in. We also vacuumed the holes because why not.

These work great for holding vapor barrier in mortar, brick or sheet foam. They are stiff and pointy enough that they can be pushed through 10mil vapor barrier material without a pilot hole (not sure if they would make it through 15mil, though). I've been able to remove them when necessary without the head breaking off (sometimes I like to reuse holes, you know).

Work, but a bit overpriced for what it is. If you don't need white clips, black is far more cost effective.

I was surprised how easy these were to use. They function very well and are very durable. I highly recommend these for attaching your vapor barrier to a block crawlspace wall.
