Garage & porch slabs were poured early this morning. Porch has a 1″ slope in 6′-‘0 to direct water away from the home. It is also important that you include a capillary break or flashing where the concrete (porch) and foundation mudsill (wood) meet. We also wrapped our 4×4 porch post with flexible peel and stick flashing. Concrete does a very good job of holding water and that moisture can deteriorate an organic material such as wood.
I’ve included a few photos of a deep energy retrofit remodel project we did last year to show the effect of what concrete can do to wood after 40+ years of exposure to moisture and no flashing!… (home was built in 1968)
