Our bar was supported on 4x4 posts and built into the patio floor. We attached the posts to the patio using galvanized brackets (Image 1). The brackets are attached to the stone floor and concrete pad with wedge anchors (Image 2). A cuff and beveled end allow the wedge anchor to fasten securely to the concrete.
A power drill and masonry bit is used to pre-drill the holes to install the anchors. Start by drilling through the stone and into the concrete pad.
Once the hole is drilled, position the bracket and tap in the wedge-anchor with a hammer. Once the elements are in place, tighten down the wedge anchor using a ratchet wrench
Insert the post into the bracket (Image 1). Level and plumb it before attaching with wood screws (Image 2).
Once all four of the posts have been secured, measure up from the ground to the proper height, and saw off each post using a circular saw. Use a long level to ensure that the tops of the post are all level.
A sheet of 3/4" plywood forms the base that will support the tabletop. We are using stainless steel and will install it later. After cutting the plywood to the appropriate dimensions, position it on the posts and pre-drill the holes that will be used for the screws.
Because the actual surface of the table will be stainless steel, the fastening screws must be counter-sunk into the plywood. We used specialized 4 1/2" lag screws (Image 1), and secured the tabletop base to the legs by ratcheting the screws into place (Image 2).
