    The Foundation Pins™ are used to permanently secure the vapor barrier™ to the foundation wall. These pins are inserted into a 1/4" hole drilled by a hammer drill. They are to be installed every two foot, two in each corner and anywhere is cut around obstructions. These pins come in packs of 100 pieces or 1000 pieces and are required for a lasting bond to the foundation wall. The heads of our pins will not break off nor will the pin come out of the hole as with other pins on the market.

    **Remember to figure enough pins for 1 every 2' and 2 in each corner (one for each wall about 2" out of the corner). It is not necessary to install Foundation Pins in concrete supports (piers).

    I purchased this product because the encapsulation installer (AFS) I hired was planning to use "nail & washer" to attach liner to foundation walls. While I am not a structural engineer, common sense tells me that if you shoot a nail into a cinder block, there is a potential to crack the block. To ensure they would do it the right way, I put it in the contract that they would use pins. While the installer is to bring his own pins, I decided to purchase a few bags to ensure the installer has enough pins to do the job properly (and if they didn't, I will sell them the bags). As a note, AFS is a reputable company; but as a caution, installers will try to get away with doing things the easy and the wrong way. Make sure you watch all the videos on crawlspacerepair.com to understand the work required to encapsulate a crawlspace.

    Excellent product, the only reason I rated 4 and not 5 stars for durability is that this is a recent installation and I will know more about durability in 5 - 10 years. I am certainly not expecting any issues based on what I've seen. Perfectly sized to work with a 1/4 inch drill bit. They are easy to install but once in, I think would be difficult to pull out.

    Work as advertised and make putting up 20mil liner on the walls much more secure and professional. Use a professional type hammer drill (I used this project as an excuse to purchased a mid-level Bosch rotary hammer)and you will be done in no time. After inserting the pins by hand/thumb, I used my soft rubber mallet to give them a nice little tap. Be a pro and don't leave this step out.

    These were very easy to use! We used very little caulking with these for an extra seal. The videos were great help. Answered all our questions and were very useful over all. We couldn't have done this easy DIY project without them. We highly recommend these products. It took us a total of 12 hours spread over 3 days to complete our small crawl space, including clean out and leveling of dirt. And we're 55! Fast delivery, too. Our total cost was 1/5 of each of the 2 bids we received from basement experts.

    These are a must have! Use a 1/4" drill bit (Wood / Masonry) and "hang" the liner as you stick it to the double-sided wall tape. This prevents it from being pulled off the tape as you work your way down the wall. Our crawlspace was real nasty, so nasty and tight I couldn't get a contractor to take the job. Glad they didn't... I did it myself for cheaper and probably did a better job.

    Absolute must to secure the vapor barrier to walls. The weight of 12 Mil SilverBack along a 5 ft wall pulled the Seam Seal tape off the wall even in an area that seemed well attached. From then on, I worked in smaller sections, reinforcing with foundation pegs every 1.5 to 2 feet. Taps in easily into 1/4 inch hole.

    Don't try the installation without the pins! They work great and really save a lot of wasted effort. While the double sided tape is great, the weight of the barrier is enough to pull it down. Working in a low crawl space, I placed the tape around the perimeter with the outer paper intact. I then worked a few feet at a time with the tape and pins. Worked well for me!

    The cement block in my crawl space was a little damp making the double stick tape not the best option. So after speaking with Larry he recommended going with the pins to secure the 12 mil and then the polyurethane caulk just above it to make a nice waterproof seal. As usual, Larry was right on the money and it worked great. I recommend getting one more bag of pins (or a tube of poly) than you think. It's better than having to reorder, pay shipping.and more importantly, having to stop your progress.

    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.

    The Answer to a 30 Year Problem

    Cons:
    WOW! You guys are the greatest. I called several times with several questions before I purchased the 12 Mil GuardianLiner™. Everyone I spoke to was very knowledgeable about crawl space encapsulation. We searched the web and I found you guys. I called and if you told me once you must have told me 20 times to seal the vents. I could not believe this would work. I did it and ordered the GuardianLiner™, the Foundation Seal Tape, the Waterproof Seam Tape, the Foundation Pins and a hygrometer. I would never have believed sealing the vents and encapsulating would be the answer to a problem we have had for over 30 years. Had we know this last year or 2 years ago, we could have saved a lot of money on insulation. I will definitely recommend you and your company to everyone I see who says they have a moisture problem in their crawl space. I have another friend whose brother paid around $10,000 to have his crawl space encapsulated on the eastern shore of Maryland. We did it for a fraction of the cost. Excellent, excellent product and excellent, excellent customer service from Bob, Caitlynn, and Larry. Kudos! Thanks again, GuardianLiner™ User and Believer
