We just did a job for the Navy removing 10x10' sections of concrete pavers and replacing them with etched clay pavers and infill pavers. This was my first experience with the Belden brand and also with clay pavers. They are much more fragile than concrete pavers. We really had to baby them because they would easily chip. I didn't have a mat for my compactor, so I just used a couple of dead blows to tap the poly sand into the joints. The sand was precompacted from the previous pavers. Just thought I'd share my experience with the clay pavers.
