Abstract
Drainage body surface units are known with conical spacer elements which are connected together via a base. The spacer elements have casing surfaces which run undulating in cross-section, comprising successive wave peaks and wave troughs. In order to guarantee as high a strength as possible with as little material usage as possible, a construction is proposed in which the wave peaks transform into the wave troughs via transitional regions, wherein the transitional regions have a smaller material thickness than the wave troughs.
