A wood railing is usually built in sections that have a beginning and ending post for support. In concrete, these supports posts will each have a plate that has drilled bolt holes. You have to drill the concrete and then install these posts before installing the railing. Be careful when drilling the concrete so you do not break or crack the material where the rail is going to be put in place. Follow these steps to install railing on concrete.
Step 1 - Decide on Location of Railing
Before you break out the tools, establish where you want your railing to go. Use a tape measure and chalk line to mark the places on the concrete where the railing will be built. On your snap line, measure from the center of the support post to the center of the end support post on a section of your railing.
Step 2 - Center the Anchor Plates
Before drilling for the anchor plates, make sure they are centered for your support posts.
Step 3 - Drill the Holes
When drilling the hole make sure it is as deep as the anchor bolt sleeve. When you have your bolt hole drilled you can place the sleeve in the hole. It is a good idea to use a rubber mallet so you don’t damage the bolt sleeve.
Step 4 - Stand Section by Section of Wood Railing
You can now stand up your first section of railing and line the holes of the anchor plate with the drilled holes. Thread a bolt into the plate and sleeve and tighten it with a wrench. Continue with each section of the railing by bolting each section until you are at the end.
Tips and Warnings
Consider making a template out of cardboard. You can trace the bottom of the deck rail posts onto the cardboard and even mark the bolt holes. Enlist the help of a friend to hold some of the components in place while you drill and secure the posts in place.
Make sure you know exactly where the deck rails are to be placed. If they are put in the wrong area, the edges of the concrete might break, and then you will have to relocate the railing to a different area.
Wear protective eyewear while you are drilling into the concrete to prevent bits of concrete from splashing upwards into your eyes.
