The patio is 12x12 and the railing kits I purchased are 6' sections, so I'll have posts every 6 feet. I'm leaning towards fastening the first rail off the house directly to the brick, then there will be one post in between the house and the corner. I figured using the Tapcons would hold it well enough, but will the anchors give me any more protection from the force of someone leaning on the rails, or would I only get that by anchoring the post to the bottom of the patio instead of the side?
