I'm installing a brick patio and a lot of the bricks are historic clay bricks, like bricks from Trenton's original sidewalks. I'm concerned that using a plate compactor after sweeping sand into the cracks between the bricks will cause the bricks to crack. Is this a valid concern? Is the plate compactor necessary or can I use something else like a hand tamper for that final stage?
Also, what are my options for edge restraints besides the plastic ones you secure with stakes?
