Looked at a job the other day. Stone and then stone dust was installed where needed by the septic contractor while on site and digging where the walk goes. Now the homeowners want their clay bricks installed (friend of a friend & its winter, so I'm game if they want to pay for my labor). 1. It doesn't seem to me that tamping was done. If I rake off a few inches of the dust and tamp the heck out of it, then rake in to final grade & tamp that, do you think it'll be OK? They already have a walk of this brick installed on the other side of the house and it seems to be holding up OK. 2. Do I put a sand layer under the brick & sweep sand in like doing concrete pavers? Its a curved walk with a soldier course of bricks perpendicular to the direction of the walk. And the bricks in the middle run lengthwise in the direction of the walk. So there will be plenty of gaps from the cuts to fill, so I'm guessing to use sand just like with interlocking pavers. 3. Do I tamp the brick after it is installed? It certainly doesn't seem as strong as concrete pavers, so I'm wondering if it can handle it, with out lots of chips, breaks, etc.. Thank you.
