Project Source 20-ft x 100-ft Black 6-mil Construction Film (Professional (6+ Mil)

Our 6-mil plastic sheeting is a general-purpose plastic film for use in a variety of construction, gardening and DIY applications. This heavy-duty plastic is commonly used under concrete slabs as a vapor barrier, on top of freshly poured slabs as a curing blanket, and as a temporary cover for equipment and supplies.
