New sealing standard

The sealing standard DIN 18195 was completely overhauled. The following five new application-related standards have been adopted for this purpose and describe the technical specifications since 01.07.2017. For the tiler, the standards 18531-5,18534 and 18535 are decisive, whereby DIN 18534 is probably the most widely used one.  It is composed of 6 sub-sections. With the publication of the new waterproofing standards, the composite tile waterproofing materials with which the tiler has usually already worked (as of July 2017) have been designated as official DIN waterproofing systems.


New series of standards DIN 18531 - 18535:

• DIN 18531 Sealing for unused and used roofs

• DIN 18532 Sealing of trafficable concrete circulation areas

• DIN 18533 Sealing of components in contact with the ground

• DIN 18534 Sealing of interior spaces

• DIN 18535 Sealing for pools and containers
