basement walls

my house was built in 1920. The basement walls are dark grey. Is this concrete, cement, or some other material? I am planning, while I clean out my basement, possible waterproofing or sealer. So I need to figure out porosity(sp) and adhesiveness.

Waterproofing & sealing is done from the outside. The only time something like dry-loc is used, is if there is a small amount of dampness. If water is entering, it's another story.

i also have an old house, 1930. The foundation is block, w/ some sort of plaster that is flaking and falling off. The exposed block looks to be extremely rough and porous. Was thinking about dryloc but didn't know if it would be effective on an old porous foundation.
