Since I've no idea what they're like "in the flesh" you'll have to make allowances for my ideas 
They could be used as barriers/fences/screens, stood on their sides.
Four on their sides would make a square enclosure ? compost, leaves, a planter. Another one on top is a roof!.
Three on their sides make a triangular enclosure - perhaps round a tree to keep beasts away.
A path in a tunnel or across wet ground. Solid enough for a wheelbarrow?
I really, really want some now.
PS one would be great to put a hotbin on.
