Putting posts in the ground is an important step in building a fence, and pouring cement into the holes will keep your posts sturdy and protected. After digging the hole, all you need to do is mix your cement and let it set. In just 1 day, you can have posts in the ground that will last for a long time!
To cement a post in the ground, youll need a post hole digger, fast-setting concrete, gravel, a shovel, and a wheelbarrow. Before you dig your hole, contact your local utility companies to make sure there are no lines running where you want to dig. Plan on making the hole for the post 3 times wider than the width of the post and 1/3 deeper than the height of the post. Use your post hole digger to dig out the hole, then layer the bottom 6 inches with gravel. Then, place your post in the center, mix your concrete, and pour it into the hole. Leave 2 to 3 inches at the top so you can cover it with soil. Although fast-setting concrete can dry within 20 minutes, leave it overnight before putting any weight on the post.

This article is about how to anchor post to concrete. This diy step by step project project is very useful, as when building a deck, a railing or a fence, you need to anchor posts to concrete. The techniques needed to attach the wooden posts to concreteare straightforward, as anyone can get the job done very quickly. First of all you have to buy the post, as to know its dimensions when buying the hardware post anchors.
The post anchors come in many forms and dimensions: from standoff post base, up to uplift post base. In addition there are regular post anchors, for home improvement projects, and heavy duty post anchors for greater stability. Irrespective of your needs, you also have to know that there are also adjustable anchors, for attaching posts to an unleveled concrete surface. They are more expensive, but at least you know you are able adjust the height of the posts, as to make sure they are perfectly aligned one with another.
First of all, you have to take a look on the concrete surface, as to see if it is level. If the concrete flooring isnt level, then you have to buy adjustable post anchors. Although they are more expensive than regular post anchors, they will allow you to adjust them to the other posts.
Next, we have to build the wooden post, that we want to anchor to the concrete platform. Consequently, you could either buy 44 pressure treated lumber or buy fancier decorative posts. Irrespective of your choice you have to adjust them to the needed length (usually around 3/1 m), before fitting them into place.
In order to cut the wooden posts we have to use either a circular saw or a wooden chainsaw. We strongly recommend you to use a good circular saw, as it is better for an unexperienced diy-er. We have used the chainsaw, as we were pressured by time.
After you have adjusted the post to the needed dimensions, you have to install the post anchors to concrete. Consequently, in most of the cases the metal anchors have to be fastened to concrete, with several plastic dowels and lag screws. Align the anchors one with another, before making the marks.
In order to dill holes in concrete, we used a good drill machinery and masonry drill bits. Make sure the drill bits are in good condition, otherwise you might damage the drill machinery. You can use sleeve bolts as well.
After we have drilled the holes in concrete, we have installed plastic anchors, using a rubber mallet. Make sure the heads of the dowels are aligned with the concrete surface, otherwise you wont be able to install the post anchor properly.
Next, after we have inserted the plastic dowels in holes, we have to drive in the screws , as to fasten the post anchor. In order to lock into position the metal hardware, we used a wrench key and 3 lag screws.
After you ensure the post anchors are locked into position, you could proceed to installing the wooden posts. Consequently, in order to anchor a post to concrete, you need to paint its bottom section with wood primer, as to make sure it will resist against moisture. Sand the bottom section with a band sander, it it doesnt fit in the anchors.
Use 1 1/2 lag screws to secure the post into position. Consequently, the last step when anchoringa post to concrete, is to drill pilot holes with a drill machinery through the holes in the post anchor. Use a thin drill bit, otherwise the lag screws wont secure properly the post.
After driving in the lag screws, we have finished anchoring a post to concrete. The wooden post is plumb, as we have used a spirit level, and it is secured properly with 4 lag screws. There are many types of anchors you could use for your project, therefore use the ones that fit your needs an match the rest of your backyard.

As I have already mentioned in the previous comments, I bought the brackets from a DIY store a long time ago. There are generic anchors, no specific brand, so I cant help you with this. The Simpson brackets should work as well, from what I see.
The step was not aligned with the deck, so they is why half of the base plate is outside the concrete surface. However, everything got covered in concrete and then tiles. Everything holds perfectly after 8 years. I was just showing my project, it doesnt mean you should install the base anchor like that. I just didnt have another option have have the railings perfectly aligned.
