Waterproofing slurries
Waterproofing slurries are used for waterproofing of buildings. Differentiation is made between mineral-based waterproofing slurries (rigid or flexible) and polymer-modified thick coatings. In addition to waterproofing slurries, other components (e.g. reinforcing inserts, sealing tapes and collars) can be used in a waterproofing system. Different waterproofing slurries differ significantly in terms of their crack-bridging performance and are thus designed for different applications.
Regulatory framework
The use of waterproofing slurries for the waterproofing of buildings is subject to a national technical test certificate (abP), cf. MVV TB, Section C 3. National technical test certificates are issued by testing laboratories officially recognised for this purpose, as listed in the Directory of recognised testing laboratories, inspection and certification bodies (PÜZ-Verzeichnis, see column on the right). The testing laboratories also carry out the corresponding testing and external surveillance. Please submit your application directly to a qualified testing laboratory.
As a European Technical Assessment Body, DIBt can also issue European Technical Assessments (ETAs) for waterproofing slurries based on European Assessment Documents (EADs) still to be developed or already existing, such as
- EAD 030092-xx-0605 Non-flexible mineral sealing slurry kit on the basis of cement
- EAD 030295-xx-0605 Flexible polymer modified mineral thick coating
Regarding the application rules for the waterproofing of buildings using waterproofing slurries, please refer to MVV TB, Section B 2.2.5.
European Technical Assessment (ETA)
To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
