Water like any liquid will follow an action known as Capillary action. This means that water can penetrated to heights and depths without exposure defying gravity. ie water can be present upto a meter but in concrete it can soak up further to 3 maybe 4 meters. Which means that water defies gravity when presented with a porous medium such as untreated concrete. Try for yourself get a glass of water hang a tissue over night across the top of the glass with just a corner in the liquid at a depth of 3 maybe 4 centimeters. By morning the level will have dropped by the depth 3 or 4 cm and the surrounding area will be wet.
In short water when presented with a concrete porous wall or Bataco uses the wall as a wick just like an oil candle would raise oil to its top. This is known as cohesion and adhesion, it occurs when the intermolecular forces acting on the surface tension which allows damp to penetrate through concrete defying gravity.
I've covered this subject many times in the blogs on this site and I have covered how we prevent this from happening. In short we change the molecular structure of the concrete such that it is no longer porous. The concrete will act as a barrier stopping rising damp. It also has the added benefit of making the structure harder and more solid.
Cappillary action was first identified during the 1600's by Leonardo DaVinci
The same is true if not more so from water sitting on the deck of a roof for that too will quickly soak into untreated concrete and then absorbed into gypsum ceilings and walls.
It should be remembered that when damp spots appear they always cultivate bacteria in the fungus or black spots that grow, this fungus is harmful to us all.
