Am redoing an entrance room and noticed damp on the inside of the grade behind where the styrofoam is. Is there anything I can do to waterproof this or is it necessary? There are no puddles of water but the dampness could harbor mold. The room is below some concrete steps and a balcony. So, the dampness is actually both at the above ane below the levels of soil outside. Didn't think concrete could get risiing damp so not sure why the upper levels of concrete are damp. You can see by the colour of the concrete where it's dry and wet. Angle in the 1st photo indoors matches the angle of the last photo (outdoors).

I have about a 6'x4' patch of dirt in front oh my house. It is kind of framed in by the perimeter of the house - front edge of the foundation and and concrete stairs. The driveway way - concrete - is on the other edges. So I don't need to build a form, I just have to fill the area. The dirt is kind of sandy. Do I need to use any rebar for this small space? My plan was to wet the sandy dirt and compact it. How deep should I make it - from the height of the existing concrete? 5"?
