Attaching posts to a cement patio can seem like a baffling job. There’s simply no way to attach them directly, as wood won’t join to cement. You need something that will join the two of them together.
But attaching to concrete really isn’t much more difficult than fastening to wood—if you use the correct tools and specialized fasteners. These four types of fastener are specifically designed for attaching to concrete, and most can also be used in brick, stone, and concrete block as well.
The steps to attach timber to concrete using masonry anchors are as follows: Step 1: First of all position your timber in place and pre-drill (if necessary) the hole (in the timber) where you want the concrete anchor to go.
Post bases, typically made from metal, attach directly to the surface of the concrete. You drill into the concrete and insert concrete screws or anchors. Once the base is in place, the bottom of the post slips right in. A variety of post bracket styles are available, and most require additional bolting through the side of the bracket into the post.
Drill right through the wood and into the concrete to a depth of ¼” deeper than the split drive anchor will penetrate the concrete. (2) Clean the hole out of all dust debris, using a wire brush or compressed air. (3) Insert the split drive anchor through the hole in the wood and into the hole in the concrete.
On the rear of my house there is a 6' x 14' porch. It is constructed of concrete blocks at its base with a concrete slab on top of the block. At one time this porch had a covering, but now it is open. What I want to do is put some deck railing around its perimeter. I plan on using 4" x 4" treated posts for the corners and railing with ballisters.
Concrete screws come in 3/16- and 1/4-inch diameter, in lengths up to 3-3/4 inches. Both hex-head and Phillips-head styles are available. They can be used in concrete, block, and brick.
The sleeves pinch the sides of the predrilled hole and get tighter as you tighten the screw or bolt. Best uses: Concrete, concrete block, mortar and brick. How to use: First, drill the proper size pilot hole (3/8-in., 1/2-in., etc.) through the wood or metal and into the concrete. Slip the sleeve anchor into the hole.
Use it only to fasten to poured concrete—never to concrete block, brick, or any other surface. And always wear safety goggles and hearing protection. Powder-actuated fasteners come in a wide range of prices, starting at about $75, but you can also rent one for about $40 per day, not including pins and loads.

In our case, we had to build stair railings and consequently we needed to attach post to concrete. First of all, you have to take a look on the concrete surface, as to see if it is level. If the concrete flooring isn’t level, then you have to buy adjustable post anchors.
Drill right through the wood and into the concrete with a masonry bit and hammer drill. Use a depth stop to get the correct depth and then blow the dust out of the hole with a turkey baster (don’t use your breath, because the dust will blow back in your face).

A surprisingly frequent, though unusual, home-improvement task is attaching wood to concrete. Two instances where this is necessary are covering a concrete slab by building a wood or wood-supported floor over it, and installing a partition wall in a basement containing a concrete floor.
