Concrete patio/stoop and door detail
I am getting ready to form our stoops & patio slabs. My wall detail is attached. I have Suresill sill pans for all doors. I am thinking I will attach a 2×6 piece of cedar or pressure treated lumber under the lip of the door sill to keep from frost heaving concrete with from catching that lip. I would cut 1/4 deep vertical cuts in the face of the board to allow for drainage path out of the sill pan down into the sub grade.
What do you think of this strategy? Is there a best practice for how far to hold down the surface of the patio & stoops below the door sills?
