Ask me anything! A common example of a permeable rock is a limestone rock. Permeable rocks are defined rocks that have large enough interconnected spaces between particles to allow the movement of gas or liquid through them.

No rock is completely impermeable, but some porous rocks like shale and pumice are mostly impermeable, because â¦ the pores are not interconnected, thus not allowing fluids or gases to pass through them.This is why shale makes a good cap-rock, and pumice floats instead of sinking.2 people found this useful. A non porous rock is a rock which has interlocking grains so water can't get into it. A porous rock is like a sponge and a non porous rock is like a stone.
