To Install a Side Door Fence in a Concrete Wall, you have to Measure the height of the new fence and determine what part of it will be attached to the concrete wall. You need to Mark this location on the concrete wall. You must Transfer this measurement to a 2-by-4 board. You can cut the board along the marking with a saw. After that, set the cut 2-by-4 board on a work bench or across two sawhorses face-up.
You should Drill holes through the center of the top surface spaced every twelve inches along the board. You can Drill the holes all the way through the board. Then, Position the board over the concrete wall within the original markings and mark the location of each drilled hole on the concrete wall. Next, Set a hammer drill on its highest power setting and use the hammer function. You have to Drill out each of the marked holes with the hammer drill equipped with a masonry drill bit that is smaller in diameter than the masonry screws so that the screw threads will have a tight grip on the concrete.
Forth, Position the board back in place and line up the holes. You need to enter 4-inch galvanized masonry screws through galvanized washers and into the pre-drilled holes. You must tighten the screws in place in order to securely fasten the board to the concrete wall. After that, mount the fence against the vertical board. You should Drill holes through the fence and into the vertical board every twelve inches.
You can set 3-inch galvanized wood screws to the drilled holes. You have to tighten them down to attach the fence in place.
