Underdrains
Underdrains
(OP)
I specified that an 8" perforated pipe wrapped in filter fabric and backfilled with gravel (18" cover) be placed beneath a playground covered with wood chips. The architect wants to use styrofoam packing peanuts in lieu of gravel backfill. Does anyone have experience using this material for backfill around perforated pipes; i.e., will it work?

In my opinion, not a good idea.

Sounds like a good reusable/recycling idea - to make use of the Architect's extras from Xmas. Maybe he'll want to throw some bows and ribbons in there also?
Not trying to be obtuse, but I'd have to do a lot of research on prior use of this material as backfill before using it in my design.
