For draining rainwater etc. from the ground behind a supporting wall made of concrete or masonry or under a concrete surface, a bed of sand, gravel, crushed stone or the like is usually used. The production of such a bed requires a great deal of work, and sometimes such natural bed material is difficult or impossible to obtain. For these reasons, artificial materials such as plastic pipes provided with openings and the like are often used for drainage purposes. In this way, however, no two-dimensional drainage or surface drainage can be carried out, which is why such an arrangement is often used in conjunction with natural materials.

To provide effective and powerful surface drainage achieve, were flat drainage bodies or drain plates developed, which have at least two walls firmly connected to one another with the formation of a gap, at least one of which is penetrated by openings through which the water can penetrate into the space. In one embodiment of a one-sided drain plate, this has a wall provided with embossed elevations without any openings and one with the formation of a gap firmly connected to this, of openings riddled wall on. Water present in the ground enters the space through the openings in the latter wall and can flow away in this. Such a drain plate is disclosed in the published Japanese utility model application 97208/1975 and described under the name "Culdrain" from Mitsui Petrochemical Industries available. A retaining wall with such drain plates is disclosed in the published Japanese utility model application 4-8905 / 197V.

The water that has penetrated into such a drainage plate flows off via drainage pipes and finally reaches a collector, for example an underground sewer.
