Pouring concrete against wood siding.

By jeremiah point reyes station q. As porous as concrete is its not even ideal that treated wood meets concrete. Wood meeting concrete in a damp area is never a good recipe. How do i treat the interface between the wood house and the concrete of the steps to make it water tight and be able to deal with the different movement of the two.

Be sure that any wood of your house doesn t end up in contact with the fill under the slab or the bare concrete. We purchased an old 1910 house a couple of years ago and the concrete porch was poured up against the house slightly above the bottom piece of siding. The best thing to do and it s the code in va is to put aluminum coil in between the wood and the concrete. The porch wraps around 1 side and part of the back where it is on the back the porch is not covered.

I would advise locating a vinyl siding company and getting them to break some scraps that they ve laying around about an inch much higher than the concrete will be poured and as far out from the house as the scraps will go. I see concrete poured against. My recommendation in this scenario would be to trim the wood siding 1 4 inch minimally or better yet 6 to 8 above the concrete area. Just tack a strip of that expansion material right against the house and pour right to it.

You don t need to frame against the house.
