Foam packing peanuts as crawlspace backfill
My coworker and I were batting around the idea of using EPS packing peanuts to backfill drainage trenches during crawlspace encapsulation. The idea would be to level the surface and support the vapor barrier using a free-draining material much lighter and less expensive than gravel. There is an online crawlspace product store (Crawlspace Depot) that sells EPS peanuts for this purpose (local pickup in NC only); they appear to be essentially the same as what we could buy at a local office supply store. I’d be interested in knowing if anyone has experience with this approach.
