Thanks - I have never seen it done, but how is that step built? Is it just lifted unto the foundation usually?Well, unless you have some obvious cracks in the pad, its leaking at the perimeter of the pad. So if the pad overhangs the foundation, caulk the perimeter where the pad meets the foundation.
Where it meets the house, there should have been a flashing installed. For some reason some people dont get that. So where it meets the house, about all you can do is caulk it. Or try using a self leveling concrete sealant. It will either fill up the crack or drip into the cold room. Or both. Or neither. LOL
Here are some pics - this is inside and outside. I have also highlighted a crack - but the leaks seem to happen where the walkway meets the Steps and where the step meets the house. The walkway also seems to have dropped.Well cant see your house so I'm totally guessing based on what is usual. The foundation of the cold room is poured (or blocks were laid up) then a plywood form was built inside the room so that a cap could be poured over the room seperately, when the other flatwork is done.. Then the form was removed. Newer houses would likely have a corrugated metal form, and that would be the ceiling you would see inside the cold room. Generally the pad should overhang 1 1/2" or so over the foundation, as a drip edge. But you will always have the cold joint where the pad sits on the wall. And where it butts up to the house some guys pour right up to the wood but in reality it ought to have a copper flashing (longest lasting, and doesnt corrode in concrete) and an expansion joint as a cushion between the framing and the concrete.
