Stair stringers: protecting base
Houghton123
| Posted in Construction Techniques on
Installing stair stringers on our porch. The first two steps are brick over concrete, with treated (ACQ) 2×12 wood stringers supporting wood stairs from there (eight risers). My question is how to treat the wood stringers where they rest on the brick. I’d like to avoid end grain resting on the brick to reduce water uptake. My original thought was to put down heavily treated sleepers (2×6 left over from the porch framing), on which to rest the stringers, but I’m afraid I’ll have to cut away too much stringer and not have enough width left below the step “notches” for strength. Any thoughts?

Interesting approach, and one that, had I thought of it, would have saved me a lot of concrete, and given me a superior design. Instead, what I've got is a brick-on-concrete pad on which the entire length of the bottom of the stringer will be resting -- similarly to what you would see for inside stairs, resting on the floor deck. I will be using a 2x4 kicker (like the one at the front of the construction you've drawn) to keep the stringers from sliding forward. I did confirm today in laying out the stringer pattern that putting 2x stock as the base on which the stringer rests would leave too little stock. I guess what I'll do is put some metal on the bottom after soaking in as much copper napthenate as it will take. Maybe I'll use that leftover 2x stock beside the stringer, with some framing connectors or side-nailed 16d nails to hold it in place.
One suggestion was asphalt roofing -- which I have. Don't know if this would be superior to flashing stock?
