Hey guys got a quick question if you have time. I've been reading many resources for interlocking pavers and have read many different ways for installation. My question is how and mainly when do you guys install the restraint edging. The one thing I believe I do know is that the restraints must be on the subbase and not the sand. Do you install the edging before or after the pavers are set in place (I have seen both examples). Any help appreciated. I do not do installations or offer this service as I need more education on it. Just looking for information. I will be looking into ICPI also. Thanks for any help in advance.
