Concret piles VS steel piles?

Here it's the english section. So I try to give my two cents in english:

— what you ask for is easy to do if you have the knowledge.
— the concret resist very well to the compression efforts, by nature.
— just what you need to do is to fill-in hydraulic-concret, encased inside a tub (easy, because a fresh concrete mixture is like a "plastic" (fluid) mass that can be molded (virtually into any shape). The tub to fill and protect the concret can be made with a plastic pvc sanitary pipe or something imho.
— for a building, we suggest steel-encased concrete piles.

But all that must be calculated by engineering.

Hope that can help.
