ABSTRACT:
This invention relates to drainage by use of elongated strips of such a physical structure that they allow an exchange of fluids between their core and the medium in which they are placed. The drainage strips are used by vertically placing them in wet soils to evacuate water contained in said soils by use of a pressure differential exerted upon the water due to the pressure of the soil layer over the atmospheric pressure in the interstices of the drainage structure.
