I was watching a crew work next door to us the other day and saw something odd so I approached the foreman to ask. They screed the sand then run the compactor over it, then install pavers in the normal way and sand as ussual.. They showed me the results after the plate running over pavers, they seemed to bed just as well as if it had been done without precompacting the sand, the reason they do this is to avoid having to be as careful with the sand, they walked right over it without leaving even a footprint. Anybody do this?????? I know this isn't ICPI approved but it seemed to make sense, I just wonder if there are any long term effects of this.
