Polyethylene quality and characteristics
Hi. I have come across various qualities of polyethylene for use under my slab. The prices vary considerably; from ~$120 to $280 for 10 mil 20'x100'. I have been told that thickness being equal, some brands will degrade in a very short period of time (matter of years), as well as off-gas significantly more. They claim that the type that is "agricultural/construction film" are cheap and not intended for under slab use. Is there truth to this, and should I shell out 65-75% more money for the "better" grade plastic? Thanks in advance.
