Great post. I have the same potential problem with cracks above 2" foam and then poly sheet VB under the foam to hold the gas. If the VB has a hole, or if the gas can burn through VB poly, then the underlying compacted gravel would happily drink up 10 gallons of gas. If the VB does a fine job of containing gasoline then the gasoline will eat foam until it hits equilibrium. It can only eat so much foam.
Now I really want to fill my sawcuts. The cuts worked perfectly and each cut has a crack in the bottom. The cracks are very thin but gasoline is so thin that it should flow through pretty well.
Again, great post. Makes me nervous and want to fill those cuts.

I did call the Fire Department on that one though and all they did was wash it out into my gravel driveway.
