FAQ: How Much Foundation Butyl Tape Do I Need?
First you need to take a measurement to get the linear feet of your crawl space's perimeter. For example, if you have a crawl space that is 50 feet long and 20 feet wide (1000 square feet) we simply add the measurements of each wall to get your total perimeter linear feet. 50 feet + 20 feet + 50 feet + 20 feet = 140 total linear feet. That's how much butyl tape you'll need. Since each roll is 75 feet, you would need 2 rolls! This will meet your 140 feet requirement. You may also want to calculate pillars.

worked well tried other brand tape did not work as well and not as much tape
This product worked better than expected. Make sure you have the plastic where you want it because once it contacts the tape it’s there.
This stuff is great!! I used it on brick foundation in an area that is very damp. It stuck very good after I wire brushed the area I installed it. I have 2 more rolls and maybe more to install. I would recommend it for your vapor barrier installation.
I followed the online videos and the tapw was adhered, I rolled it and after 5 days the tape started coming off of the concrete block. I was disappointed and hoping for so much more. I will be contacting customer service, hopefully my other rolls dont do this.
Great tape. Holds great. Sticks great to cinderblock.
Tape won't stick to Cement wall!
We used a wire brush and Dollar Store LA's Totally Awesome Cleaning Vinegar to clean the poured concrete surface prior to applying the butyl tape. Other than areas of the concrete with rough surface, the butyl tape stuck tenaciously to the concrete. One must be careful to align the vapor barrier to its proper position prior to sticking it to the butyl tape; once the vapor barrier touches the tape, it is stuck. We used a Freeman PSSCP Pneumatic 3" Single Pin Concrete Nailer to drive Ramset 1" Powder Fastener Pins With Washers through the vapor barrier at the middle of the butyl tape at 16 inches on center, to make doubly sure the vapor barrier would not come adrift from the concrete.
worked beautifully. Sure is sticky!
Works awesome! It stuck strong to an old dirty block wall and held up my poly just the way I imagined.
