European Technical Approval

Certified: wedi Products with CE Marking as Sealing System f

Bathrooms and wet rooms are regularly exposed to water. It is therefore essential to have regulation-compliant seals for floors and walls. The wedi building boards that have proven themselves for 30 years and the wedi Fundo floor-level shower elements have already been a certified sealing system for several years and have also received the general test certificate. In addition to this, these wedi products have now received the European Technical Approval for the "sealing of floors and walls in wet rooms". The CE marking that can be found on the packaging or the product itself shows that this is a sealing system that has been certified at European level.

The tested system "building board / Fundo" comprises the components wedi building boards, wedi Fundo floor-level shower elements, wedi sealing tapes, wedi sealing corners, wedi sealing sleeves, wedi 610 adhesive sealant and the wedi 320 thin-layer mortar necessary for the laying of the building boards and ceramics. In addition, wedi has had nine other tile adhesives from well-known manufacturers tested in combination with its system.

2-year intensive testing process
According to the Construction Products Directive, the usability of products that can be freely traded in Europe is to be ascertained on the basis of harmonised European standards or European Technical Approvals (ETA). In the case of "seals for floors and walls in wet rooms", this is ETAG 022 T3. The testing process that this involves is extremely demanding and extensive. It not only includes the testing of the products for different criteria, such as water impermeability, but also the auditing of the entire production, the manufacturer's own testing equipment, the flow of goods and much more besides. This intensive testing process took two years at wedi. At the end, the Deutsches Institut für Bautechnik (DiBt) certified that the sealing system "wedi building board / Fundo" completely fulfils the requirements of the relevant EU directive.

The manufacturer wedi points out explicitly that these are standard goods that have gone through the testing process. Not some kind of special products. "Anyone who buys wedi products can be sure that they are getting a sealing system for wet rooms with CE marking."

CE marking
The CE marking that wedi applies to the approved products or their packaging shows the customer that they are a tested sealing system for wet rooms. The important information for consumers is presented in the approval as well as in the declaration of performance (DoP). These can be obtained at in the download section.
