I had a similar thought to filling it, but would suggest a self leveling driveway filler manufactured by sika. its like rubber in a tube. More expensive that foam but adds rigidity where foam doesn't. Also it is a misconception that filling something with foam adds boyance. A hollow hogs capped at both ends will weigh more filled with foam than filled with air hence reducing boyance. Want it does do is prevent water, a much heavier material, from filling the space if a hole is present.
l like to buy stuff and no I don't do payments!
