I have a client wanting to use the concrete pavers as edging for all of his flower beds. Never dealt with these much but some of my employees have so don't want to pass up the work. I measured it out to be 270 linear feet. Since they are just being used as edging and no raised beds or anything there is no need to stack more than 2 blocks high...planning on burying the bottom one a couple of inches to keep the bermuda from going under them. How do I go about figuring out how many blocks it will take...oh yeah just the larger blocks from Home Depot is what he is wanting. Also what base is needed if any? And I know every region is different, but an idea of cost would help...or atleast a method of bidding this. Immediate help is appreciated. Thanks so much.
