Precast seps and risers
I am replacing a set of bull nose precast concrete steps and the risers(5 total stairs). The old steps were 5' long with a 7" rise and 12" tread. The new steps are the same size. the problem i'm having is with the new risers. The rise on the old risers were 7.5" and the rise on the new risers are 7". With the rise on the step and rise n the risers being the same it doesnt allow me any room for a bed joint. I don't want to lay my steps high to my risers because i know the problem will get worse as i go up. Iv'e seen it done and it looks hacked together. Do they still make risers with a 7.5" rise. Do I have any other options to make this work? or do i need to find 7.5' risers? Any other suggestions? I don't want to cut the risers either im worried about exposing any rebar.

Check your dimensions. You appear to contradict yourself with what you wrote.

Yes you should be able to find 7.5" riser. What is the local code?

If I lay my first step which sits on the ground level with the first rise on the riser..the next step would have to be layed completley dry to be level with the riser behind it, because the height of the step and the height of each rise are the same. I haven't had any luck finding any risers other than 6",7",or 8". I've been told they don't make the risers with half inch increments anymore. I think if i looked hard enough I could probably track some down but I think I am going to keep my bed joints as tight as I can and work with what i have on site already. Thank you for your reply's!
