    Foundation Seal Tape™ (FST) is used to seal the vapor barrier to the foundation wall. When installed to a completely dry & clean foundation wall, the bond is good enough to hold the vapor barrier to the wall temporarily (several hours/days) until the Foundation Pins are installed. If the foundation wall is wet in the area it will be installed and it will not bond then a polyurethane caulk must be used. This tape is 1.5" x 108' and has a reinforcement inside the tape to eliminate stretching like bubble gum. This is important because without the reinforcement this tape is impossible to apply in a crawl space. Most all other tapes on the market, similar to this one, do not have the reinforcement.

    IMPORTANT-
    Using a wire brush will create dust and debris that fills the pores of the block. When this happens the FST loses most of its grip to the block due to adhering to the dust in the pores rather than the block itself. No matter how much soft brushing you do AFTER the wire brush the FST will likely not stick.
    **During cold month installations this product must be stored indoors prior to use. This product is not meant for installations that have WET or very DAMP foundation walls please use the polyurethane caulk.



    **We always recommend getting a few tubes of Poly Caulk to make sure you have enough material to get a good seal to the foundation and to handle any damp areas on the foundation walls. Remember when you figure your FST to include going under beam pockets, ductwork that is touching the foundation walls and the access door.

    I have used this tape on several crawlspace encapsulation projects and it has always performed flawlessly. I have used it in various environmental conditions including very wet crawlspaces. I have never had a problem with it not sticking to the wall. I do clean concrete block walls with a stiff bristle brush, not a wire brush, prior to application of the tape. I also make sure that the walls are not damp to the touch. This tape works great and really bonds well to liner material.

    This foundation seal tape is very good at sticking to everything. You can pull it tight and it doesn't rip. Makes it easy to hang your sheets of plastic. I used silver back 20mil and didn't get back in the crawl for a couple days to get the foundation pins in. When I got back to it. Everything was still stuck to the wall. Durability is unknown, I've only had it up a couple of weeks. The wall has to be pretty clean for it to stick but doesn't have to be spotless.

    This tape works exactly as advertised. Sticks well to concrete (as long as it is dry) and really sticks to the vapor barrier. I try to line the vapor barrier up carefully over the tape, press in place and then apply a little 'heat' by rubbing a gloved hand over the area. Almost impossible to get the vapor barrier unstuck after that! I also order extra Foundation tape when I want to double seal a seam: foundation tape between the two layers underneath and seam tape over the top of the joint. Works great for peace of mind in wet areas or those hard to reach places where you never want to wedge your body again!

    I had ordered the Foundation Tape Seal and the seam tape to encapsulate my crawlspace. I did not order enough and thought I went to the same place to order more but it was definitely not the same product! The butyl tape from the other company did not stick as well even after rubbing it hard multiple times. The tape from the crawlspace repair stuck the first time. Also, on the other crawlspace companies tape I was able to lift the vapor barrier off to reposition it several times. I did not get the feeling that the tape was going to hold the vapor barrier up down the road. Save yourself the worry and buy this tape but make sure where you stick it and what you stick to it is where you want it. It definitely will stay where you put it!

    I purchased this product because the encapsulation installer (AFS) I hired is planning to use "sealant" to attach liner to foundation walls/supports. While I don't think there is anything wrong with doing that (especially for wet crawlspaces), I think the tape will give the work a more professional look. To ensure they would do it the right way, I purchased a few roles of the tape and will ask the installer if they would use instead of their sealant. So while I have yet to use the product, the videos on crawlspacerepair.com show it as a quality product and easy to use.

    This tape reminds me of the type of advise used in automotive, specificly to adhere the windshield to the frame. The tape sticks well to concrete but make sure you get it right the fist time as it is hard to remove from the plastic wrap and after pealing it from the concrete it won't stick well the second time. If I could make a recomondation I would suggest a wider backer than the tape membrane to ease the removal as it it very difficult to get an edge started.

    I was surprised how well it stuck to the cinder block wall. Our crawl space was quite dusty before the liner was applied. It can be unforgiving if you need to pull the liner off the tape in order to smooth out wrinkles as you are moving along the wall. As indicated in the video only apply a small length of liner to the tape at any one time to minimize wrinkling of the liner.

    The "too sticky" tape!

    Rating:
    Pros:
    Cons:
    I say "too sticky" because this stuff is really sticky. If you stick it to the wall and don't start pealing off the top layer, it's a real pain in the neck. Before you stick it to the wall, start the top layer pealing off as well, then make a 'loop' and stick it back on so it's easy to get hold of when you are ready to start hanging your wall liner. Truth be told, it's not too sticky, but when it's stuck to your fingers, you may beg to differ.

    This stuff is very sticky. So don't let it stick to itself. But when I installed my vapor barrier, the tape did not stay stuck to the block wall. You'll need to install Crawl Space Foundation pins as you go to keep it from falling. I will probably have use some polyurethane caulk to seal the top edge of my vapor barrier where the seal tape did not seal.

    This product works great. Absolutely essential if you are trying to affix the 12 mil barrier to a brick foundation in a space with 16 inch clearance. You have to be a contortionist. This product was strong enough to hold the plastic in place so I could belly crawl down the line. Because I had uneven brick to work with I had to go back through and put a foundation pin every 12 inches. It would not have been possible without this great product.

    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.

    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.

    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.

    I used Foundation Seal Tape to seal the existing vapor barrier in my crawlspace to the concrete side wall. Now I have as close as a person can get to a completely sealed crawlspace floor. In the spring and fall our water table comes up and makes the ground moist. Now I have a complete seal. Product was very easy to install. It stuck well to the concrete wall and the plastic sticks to the tape very very well. I have checked out the "stickyness" after one month and the tape is doing its job great. No releasing anywhere. In reality, it seems like it has a better grip now than the day I installed it. I can lightly pull on the plastic and the plastic will not come off the tape, and the tape will not come off of the concrete. So, Foundation Seal Tape works as the company says it will. I recommend this product to anyone wanting a total vapor seal in their crawlspace. MP North Idaho

    I finished encapsulating my crawl space and the tape worked as advertised. I did find difficulty in pealing off the protective strip. I will know in about a year if the encapsulation system lives up to expectations

    Good for center block, but not good on red brick

    This is some really strong tape. If it touches the vapor barrier, it is easier to leave it than to pull it off. The tape works really well on clean center blocks as long as you only attach it to the block and do not pull it off. However if you have red brick, the dust in the brick covers the tape and it looses its adhesiveness. To cut, use heavy duty scissors and a razor to peal the brown paper from the tape. I used the tape and polyurethane caulk. I strongly recommend this product.

    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.

    Thick and gummy, good for sealing vapor barrier to concrete block. If concrete surface is pitted or irregular, however, I would recommend using polyurethane caulk instead.

    This foundation seal tape was outstanding. It sealed and held under tough conditions far better than I expected. I was most impressed with its thickness and it's holding power. I used a bit more than originally planned because I had several uneven surfaces to seal around. I used the tape to add thickness so the vapor barrier didn't have to be cut perfectly or stretched into small wall/support voids that needed to be sealed for my project.

    This tape is easy to dispense and cut. I use a utility knife to cut and then lift the backing off of it. Be sure to clean the block where the tape will go. you do need to press it down to get a good seal and stick. I used alot more than I expected. measure the door way and any other vertical obstruction where you will have to run this tape down the vertical. I had 2x4's nailed to my block where all the electrical wires ran down. used up 25ft right there.
