According to DIN 18533-2 Section 7.1.2, a variety of materials are possible for the waterproofing of components in contact with the ground with plastic and elastomer membranes, e.g. ECB membranes, PIB membranes, PVC-P membranes, EPDM membranes, FPO membranes and others.
There are designs with plastic and elastomer membranes in accordance with DIN 18533 for all water action classes, including W2.2-E (pressurized water with an immersion depth > 3m). The specific waterproofing design is based on DIN 18533-2 Section 8.3. In principle, the installation is always single-layered.
