Concrete at base of shed (below ground) damp
The shed has about 5ft deep of concrete and about 4ft of that is below ground. Right at the bottom it seems damp, not sure if water is coming through or it's just condensation from rain water in the ground.
Is there a way to seal the cement from the inside?
There is no membrane between the outer concrete and the ground earth.

Is this a footing, poured wall, slab? Seems awfully thick for a slab. If you have water or moisture at 4' deep, I don't see how that can affect the slab itself. Certainly there is subterranean water that deep that does not extend upward to the surface.

It is doubtful any interior fix will be effective. Water can only be eliminated from the outside. Interim measures would include grading away from the building, gutters, downspouts with exits at least 4' from the walls. Basically get rid of the water.

So, there's one section of rotting frame wood.
I can dig the ground more and put a negative slope.
How can I remove the rotten horizontal wood below the stud? Just cut it out and slot a new one in?
The main problem is that this area of land, with the shed, is at the bottom of a 100m high hill in the back. So, all rain runoff collects down there at some point. But it still shouldn't come through concrete unless there are cracks in the concrete?
