We had to remove a few pins for my drilling quite deep enough, drill again, and reinstall.

TIP: We rented a hammer drill to make this happen and it worked amazing compared to using a motar bit in our regular drill. Such a time saver!

BONUS TIP: If you have space and a helper run a shopvac and place the tip about an inch below the drill spot for instant cleanup.

 

The vapor barrier was Very strong and the shipping was very fast. Would highly recommend.

I had a roll from a previous project completed over two years ago. Dug it out of hiding, and came off the roll easily, held like it did when new. The best tape I've found to work with heavy vapor barrier installation. Yes, it's pricy, but consider having to go back into the crawl space to repair seams that came loose. Once is enough in my opinion.

This tape is a must have for doing a crawlspace job correctly. Great quality and works well.

I probably didn’t need to use Felt 550 under 20 mil silverback, but I’m happy I did. Since radon mitigation was critical and added storage space was needed it provided the most durable solution with additional protection from any rocks I missed. It did make it much cleaner to install the vapor barrier which is a real plus.
