A drainage body is disclosed which comprises at least two substantially identically shaped surface units, that is a base unit and a substantially identically shaped top unit, which are combinable with one another in an installation spacing by way of spacers. It is proposed to form the surface units to be substantially interlockingly stackable in such a manner that the installation spacing of the surface units is considerably larger than their spacing in the stacked condition, whereby the spacers essentially have, for example, a frusto-conical or frusto-pyramid shape with a circumscribed cross-sectional area which becomes smaller as its distance from the surface units increases. As an alternative to this, it may be provided that the spacers are disposed in such a manner on the surface units that the base units and the top units are layable so as to be overlapping one another in the manner of a masonry bond. As a result this creates high stability with simultaneous space-saving storability and transportability.
