Addition cement foundation below grade, patio pour?
We just moved in to a home about a year ago so I am still in the process of finding things out (and learning what’s terrible and what’s not…), but I had a question regarding pouring a patio at grade if the cement block of our foundation is below grade.
The blue metal is what I assume to be flashing to cover the treated wood from the elements, but you need to go down about 2-3 more inches to reach the end of it where the cement block begins.
Can I have a cement patio poured just below the start of this flashing (expansion joint between) and below the door exit, or do I need to go further down to where the block foundation begins? If I need to go downward, that takes the patio below grade of the rest of the yard, which I don’t think is something we want. If I cannot pour the patio against the house due to the depth of the block below grade, can I pour it about 2 feet out and fill the gap with stone? Not sure what I would do for a step down onto the patio at that point, though… maybe just a couple slabs of stone, or something to land on?
