Posts Into Concrete


Hi,
I would like to install a short run of handrailing up some 2" thick bluestone steps, (4 steps) that are set in stone/concrete. For the posts connecting the handrail/ballasters I was thinking of attaching two 4x4 PT posts (one at top and bottom) to the bluestone using an anchor plate. I wanted to drill into the flagstone, down into the rock/concrete, put in epoxy, a sleeve, then a bolt to hold the plate down. My question, is this doable? Is that strong enough for a handrail? I can't really dig hole outside the steps for the posts, because there is a lot of uneven concrete and rock. Any thoughts?

You can’t “easily” dig to the outside but that’s were I’d like to see the post.

Nothing you do on top will be "Rock Solid".

A picture would be nice.

build a hollow box post with a 1" piece of allthread rod. rod drilled into tread/ step area with hydraulic cement poured around it at the step. I like to drill the hole large enough to have a nut with washer poured into the hole threaded on the rod. then a box post with a rabbit/mortise at the top that a plate will sit on with a center hole for your allthread to go thru. washer and nut and torque will lock post in place. finish post with top cap of your choice
