Construction adhesive at the top of the block. A good solid line of it. Don't scrimp the first time. Push plastic against it and rub. Do not disturb the joint. Hope this helps. I did this on my crawl space and did it ever make a difference on the amount of moisture coming through the wall! Many times when a foundation for a crawl space is built it is not damp proofed. It is not a requirement of code to damp proof 'non living' spaces. So the contractor does not do it but later on the homeowner wonders why the wall is moist or damp to the touch. Good for you that you are doing this. Do not attach to the plate. It is my personal feeling that if attached to plate it can lead to the plate becoming more entrained with moisture and maybe failing earlier. Or what is in contact with the plate. Hope this helps.What is the best way to bond plastic sheeting to concrete blocks?
From the outside, right? The ';tar'; damproofing or bitumen is the best job. You can then place the plastic over the tar. The key is getting the tar as close the grade line as possible. Most moisture entering foundation comes from improper grading or downspouts that are not properly extended. Make sure grade pitches properly away from foundation. Also extend downspouts 5 feet from foundation.
spray tak or 3M spray adhesive spray it on the concrete and on the plastic and wait 5mins before sticking
Using paint on the block and apply the plastic sheeting.
