Great product. Excellent adhesion yet is removable/reworkable. Aside from the obvious use on long seams, I used multiple small strips to cover both inside and outside corners by overlapping in several different directions.

I was given a quote of $4500. to install a vapor barrier in a 35ft.x45ft. crawlspace, so I decided to try to do it myself. I found crawlspace repair .com on the internet. I decided to use the 12mil. vapor barrier instead of the 6mil. that the quote was for. It was not hard to install, if fact it only took a few days by myself. The end result looks very professional and total cost was less than $1000. This is an excellent product and I would recommend it to all.

The foundation pins worked great. I installed one pin every two feet along the perimeter wall and within two inches of every corner. Three pins were installed on each 8"x16" cinder block pier. They give a nice professional finished appearance.

I'm sealing the crawl space on a new house under construction. I applied the tape and vinyl liner to the foundation walls prior to the wood floor system being installed. I made sure there wasn't any blobs of mortar in the way of the tape. The block was dry so the tape had good bonding strength. The excellent adhesive strength of the tape allowed me to install the tape along the entire wall section (60')and then hang the vinyl prior to drilling for the pins. Two days later I noticed the tape pulling away from the block in some of the corners. Since I had ordered extra foundation pins, I went back and installed pins closer in the corners as well as in between all of the original pins. Therefore, pins are every foot along the walls. I feel confident the vinyl will not come down now.

Nice wide tape, easy to work with, would buy again. Fast shipping.
