Sandbaggy Black 6 Mil Plastic Sheeting is a 20 foot by 100 foot roll that gives you 2,000 square feet of stretchable, tear resistant film. Use it as a vapor barrier in crawl spaces and under laminate flooring, or as a cover over building materials and stockpiles.
Farmers, contractors, and DIYers who want domestically made black poly film for moisture control and general covering will get the most from it. The sheet comes 20 feet wide, so measure your space first and trim it to fit with a pair of scissors.

A 2,000 Square Foot Roll for Crawl Space Floors, Stockpile Covers, and Underfloor Moisture Control
This roll is a match for your project if you need one sheet to do several jobs across a property or a build. At 20 feet wide, a single pass covers most crawl space bays or a full room of subfloor without a seam, which matters when the goal is to keep ground moisture, dampness, and condensation away from framing and flooring.
Outdoors, the same width drapes over a soil, sand, or gravel stockpile, or over stacked lumber, with enough extra to weigh down along the edges. The film stretches before it tears, so it tolerates being pulled over corners and uneven ground better than brittle sheeting does. You can cut it with household scissors, so fitting around piers, posts, and odd shaped piles goes quickly.
What is left over can be folded and used again. If you are lining a crawl space that sees regular foot traffic or has sharp rock on the floor, step up to a thicker crawl space moisture liner. For covers that need grommets and tie downs, a reinforced tarp will serve you better.
What to Expect from the Sandbaggy Black 6 Mil Plastic Sheeting in Real Use
Verified purchasers describe this sheeting as very heavy plastic that is useful for many purposes, and several confirm that it performs as described. That is consistent with what the product is: a general purpose 6 mil film sold for agriculture, construction, and home projects.
In practice, expect a sheet that stretches under load and resists tearing when you pull it into position. The manufacturer states it has 50% more tear resistance than many imported options. Scissors are enough to cut it, so you will not need a blade for fitting.
The black color blocks light, which is useful for covering stockpiles and stored materials. It is the same reason many growers use dark film for landscape and ground projects. Plan for the size. Twenty feet of film is easier to place with a second person, especially outdoors in wind. Weigh the edges down as you go.
The roll is reusable, though polyethylene does wear out. Like other jobsite plastic, it will eventually break down with repeated use and exposure, so inspect it before each new job.

Frequently Asked Questions
Can you use 6 mil plastic sheeting under laminate flooring?
Yes. This sheeting can be laid under laminate flooring as a vapor barrier to keep moisture and dampness from the subfloor or slab away from the flooring above. Roll it out across the room, trim it with scissors to fit the walls, and overlap the edges where two pieces meet. The 20 foot width covers most rooms in a single piece, which reduces the number of seams.
Can you use black plastic sheeting to cover a stockpile?
Yes. Covering a stockpile is one of the intended uses for this roll. Drape the sheet over the pile of soil, sand, gravel, or other material and weigh down the edges so wind cannot lift it. The 20 foot width gives you enough material to reach the ground on both sides of a typical pile, and the film stretches over uneven shapes instead of tearing.
Is 6 mil plastic sheeting reusable?
Yes. You can fold or roll this sheeting up after a job and use it again. It stays usable until the plastic itself breaks down, which depends on how hard the material is used and how much exposure it gets. Before you reuse a piece as a vapor barrier, check it for holes and tears, since any opening lets moisture through.
