Fundo sloping board

„Extension for the Fundo Primo, Fundo Riolito and Fundo Riolito neo shower elements“

Product information

The wedi Fundo sloping board is used for on-site extension of the Fundo Primo, Fundo Riolito and Fundo Riolito neo shower elements and therefore for the expansion of shower areas. It is available in two different thicknesses; with 1.00% or 1,70% slope.

  • The blue XPS core is 100% waterproof and still functions if it becomes damaged
  • abP* approved: wedi 610 seals joints between boards and makes them waterproof without the need to use any other products. As it is not necessary to use any other waterproofing materials, the tradesman benefits from increased security and a shorter application time.
  • The cement-coated surface forms an incredibly strong base for adhesive thanks to the integrated fabric.
  • All of our building board systems provide long-term protection against mould and fungi, offer fantastic insulation and therefor save energy costs.
