Overlap the seams by no less than 12 inches and secure them together with the poly pvc tape.
Plastic sewer line on crawl space floor.

I did my entire crawl space 2500 sq ft with this plastic and could not be happier.
I m 55 yrs old and did it all myself including loading unloading and cutting these rolls.
Cut the sheets to size allowing 12 inches or more along walls.
Beginning at one side of the crawl space lay down 6 mil or thicker polyethylene plastic over the entire crawl space.
It can also help create a more suitable storage space for homeowners.
Second if gravel is on top of the plastic we can t see that the plastic was placed over an adequately smooth sloped crawl space floor the risk is future puddles of water that collect on top of the plastic but hidden from view under the gravel an ongoing crawl space water and moisture trap.
Primarily plastic is installed in crawl spaces to residential buildings to create a barrier against moisture or vapor.
Even in the most arid areas of the country mother earth constantly releases water vapor which likes to seep into your crawlspace through.
A floor drain can be installed but might not be necessary.
We carry all the tape and adhesives you need to securely install your crawl space wall and floor liners to create a powerful moisture barrier.
Plastic sheeting in your crawl space can serve a number of useful purposes.
This approach helps minimize the risk of mold or mildew intrusion into the home.
In many cases water heaters and furnaces are installed in the crawl space.
Plenty thick and not too hard to work with.
If the existing crawl space floor is dirt some improvements might be undertaken to give the homeowner the best floor possible.
