I was reading in a post below about limestone screenings being used as a bedding layer for pavers. I can understand what you guys are saying about limestone, but down here on Long Island many of the big companies swear by using bluestone screenings. I have only tried it once and it seemed to work out fine with the exception on the final interlock but hey i had to try it. (on my own yard) I only use sand in my customers installs. The thing that confuses me is.... interlocking properties aside, it seems like ur issue with the screenings are that the limestone will dissolve over time. Does this hold true with these blue stone screenings. I just cant imagine why people down here spend $50 a yard on this bluestone , as opposed to $24 for good sand. It seems alil rediculas to spend twice the money on a material that isnt intended to be used.
