The product stuck very well to the 125 year old soft bricks in my crawlspace. I just dusted the bricks with a paper towel and had no problem with adhesion.

Just wanted to send you a quick note to let you know how well the Foundation Seal Tape worked for my vapor barrier. After brushing the block and insuring they were dry, the tape stuck well and allowed me plenty of time to hang the vapor barrier and install the Foundation Pins. This barrier has been installed for a month now and I have had no problems with the seal. I would recommend the Foundation Seal Tape and Foundation Pins to anyone who is installing a crawl space vapor barrier.

Thanks for the follow up. Your products were more than what I expected, but I can't say enough about the excellent support I received from your staff. I'm hoping to use your products on another project I may have coming up soon.

All materials and supplies were as advertised. The foundation tape, the water proof seam tape, and the vapor barrier fasteners worked exactly as advertised. I could not have been more pleased with the products.

Found all the products I have used from Crawl Space Repair to be high in quality along with fast shipping and packing. I tackled this job by myself and was still able to accomplish a great job when finished (although a little soar in the joints)and a little more time to finish.....lol. The foundation seal and waterproof seal tapes worked great and had a lot of holding power. I was impressed with the foundation tape as it stuck very well to the cinder blocks after lightly brushing them off. The foundation pins were easy to install and the 1/4 inch holes were surprisingly quick to drill in the cinder blocks. Makes for a neat job and extra holding power for over a longer period of time. The vapor barrier I used was the 12 mm and very strong and was amazingly easy to work with and lay down in sections,even on the walls of the crawl space. Now I have a crawl space that is well lighted and clean with less moisture content. I have even noticed some differences in the temperature of my house. It seems to stay cooler longer in the warmer temperatures,outside, we have been having,which means lower power bills. Been turning the air on in late afternoon and turning it back off in early evening and it stays a comfortable temp inside. We shall see what happens when summer temps come around,but it still should be an improvement.
