  • Relationship of void ration to rock size/shapSoil

     · Pack them as tight as possible and you will have an identical ratio of voids to solids. More important is the range of sizes. Add ball bearings to the bowling balls and they fill up a portion of the original void space. Of more importance for filtration is the grain size of adjacent materials to minimize migration into your filter material.

    As I remember my admittedly long-ago soils classes the size will do little to influence the void ratio. Imagine simple spheres like ball bearingMost details that I have seen call for 1" or 1.5" clear stone. I generally use 1.5" clear stone.
