Yes, objects can absorb water if they are porous or have spaces within their structure for water to seep into. Materials like sponge, cotton, and paper are examples of objects that can absorb water.
A porous barrier is a barrier against the movement of one type of objects that is not a barrier to the movement of another type of objects. A "real life" example would be a picket fence, which stops motion of objects, such a s adult humans, that are larger than the distance between the pickets but not those of smaller objects such as snakes and insects. However, the most common use of the phrase is in engineering and physical chemistry, specifically in osmosis and reverse osmosis technology, battery design, and other electrochemistry. In these fields, porous barriers have been devised that permit the flow of water but not electrolytes, of cations but not anions, etc.
There are two types porous and non porous. You can also seel porous concrete to make it non porous.

glass, plastic, metal. I don't feel like thinking too hard so that is all I will say.
Silk is porous -- it absorbs liquids.
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
more porous
The story proved to be quite porous. Lava is a porous rock.
Stainless steel is not inherently porous, as it is a non-porous material.
All natural store is porous and needs to be sealed. Travertine is the most porous over marble and granite
