Concrete Poured Against Wood Siding

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.

Concrete poured against wood siding.

Wood meeting concrete in a damp area is never a good recipe. This is an isolation joint material used between concrete and what the concrete is being poured against. You can use a product called iso strip off. 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.

Further water sitting on the concrete can seep through the joint between the concrete and the siding and cause dry rot in the siding and in the wood members below. The top 3 8 inch of the iso strip is perforated so you can peel it off after the concrete is hard then you can caulk this groove making it water. 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. This is just a quick video for my friend who is building a home.

The porch wraps around 1 side and part of the back where it is on the back the porch is not covered. It lets the concrete expand and contract freely. As porous as concrete is its not even ideal that treated wood meets concrete. I see concrete poured against.

Anyplace where wood meets the ground or concrete the lumber must be pressure treated. The best thing to do and it s the code in va is to put aluminum coil in between the wood and the concrete.
