Advice on adding 2 more steps to builder provided concrete steps

Hi Everyone, I have decided to cover my front porch, steps and landing area between the steps and sidewalk with flagstone (wet lay using mortar). There is one slight problem ...the builder's concrete steps ends a little high and the drop is too much and 2 steps are needed as you can see in the pictures. I have removed the retaining wall + coping steps combo on the left and right side that the previous owner had installed. I will need to build 2 steps and a landing area (please let me know if there is a better solution) to install flagstone on them as well and have a consistent fall per step throughout. I also thought about buying the solid blocks (6"H x 16"D x 72"W) but they will not sit flush with the builder's steps since the concrete juts out right in front of the railings (see pictures). They jut out almost 4" so I'm thinking a new concrete pour is the only solution. Am I correct? Questions: Should I use expansion joint strips between the builder steps and the 2 new steps I am building or should I join them together? If I'm joining the old and new steps together, should I drill some deep holes (6-10") and insert rebar in there and have it stick out like 1-2 ft and bury that rebar with the new concrete from the new steps? Is applying concrete bonding glue on the face of the old steps a good idea for adhesion? Should I use an expansion joint strip between the landing pad and the city sidewalk? I assume yes but want to be sure. Is 4-6" of gravel under the concrete base (tamped down of course) sufficient? Will this make the builder's concrete steps weaker or have it be against code by any chance? Pics: https://imgur.com/a/DcFYtQc submitted by /u/TwistedE [link] [comments]

Hi Everyone,

I have decided to cover my front porch, steps and landing area between the steps and sidewalk with flagstone (wet lay using mortar). There is one slight problem ...the builder's concrete steps ends a little high and the drop is too much and 2 steps are needed as you can see in the pictures.

I will need to build 2 steps and a landing area (please let me know if there is a better solution) to install flagstone on them as well and have a consistent fall per step throughout.

I also thought about buying the solid blocks (6"H x 16"D x 72"W) but they will not sit flush with the builder's steps since the concrete juts out right in front of the railings (see pictures). They jut out almost 4" so I'm thinking a new concrete pour is the only solution. Am I correct?
