I have never seen polymeric sand used by a real paving contractor on a big job (20-40 acre industrial site with 20,000 to 100,000# loads, roads or streets) with 80 to 100 mm thick interlocking concrete pavers. - Tight joints and fine sand with a 1" coarse sand setting bed.

Best to avoid it unless someone specifies it.

It was made for DIY'ers.
