They are used under house and building foundation slabs, as well under concrete sidewalks.

Measure the length and width of the slab, and multiply the two to determine the square footage of plastic sheeting needed. Add 10 percent for waste and overlap. Starting in one corner of the slab, roll out the vapor barrier all the way to the other end. Cut the sheeting off when you reach the other end. Start a new r
