I'm digging a 2 feet deep french drain a few feet away from the house. I'm wondering if instead of gravel I could surround the 4" perforated pipe with packing popcorn (or peanuts, or whatever they are called). I'll be backfilling 1 foot with dirt on top.

I know that gravel works. The question is: is the popcorn really a good idea or am I going to see problems in the future.
