Fundo Substructure Set

new

„for Fundo shower elements with point or linear drainage.“

Product information

The new wedi Fundo substructure set brings the flush-to-floor showers in the wedi Fundo range to the desiredheight even more easily. Each set contains: two substructure elements with heights of 30 and 60 mm and threepreformed drain mount rings for point and channel drains. Substructure heights of 30, 60 and 90 mm can be easily and reliably achieved with this combination. The two substructure elements can be cut to the exterior dimensions of the appropriate wedi Fundo shower element directly on site. Another benefit: the opening for thedrain pipe can be implemented in any direction you like. The new wedi Fundo substructure set range is equally suitable for Fundo shower elements with point or linear drainage in any size.

Scope of delivery:
1 × EPS substructure element, 60 mm thick 
1 × EPS substructure element, 30 mm thick 
3 × drain mount for point and channel drains (vertical, horizontal, Mini Max)

Technical properties Fundo Substructure set

The Fundo substructure set is delivered as a kit. A mount height of 30, 60 or 90 mm is produced with the help of the two elements with different thicknesses. The 3-part drain mount precisely incorporates the various drains.

The Fundo substructure set can easily be shortened to the necessary dimensions in length and width. The appropriate variant and number required depend on the dimensions of the Fundo shower element selected. Order 2 × Substructure set 900 × 900 mm for 1,800 × 900 shower elements, order 2 × Substructure set 1,200 × 1,200 for 2,000 × 1,000 shower elements.

Freely selectable drain position (depending on the Fundo shower element selected)

The recess for the drain mount and drain pipe is created on the construction site.

Areas of use Fundo Substructure Set

  • The wedi Fundo substructure set is to be used as a height adjustment Base for Fundo shower elements. It is approved exclusively  for use in the floor below wedi Fundo shower elements, in rooms with residential occupancy. The wedi Fundo substructure set isavailable in the dimensions 900 × 900 mm, 1200 × 1200 mm and 1500 × 1500 mm. A mount height of 30, 60 or 90 mm can be produced.
  • The wedi Fundo substructure set is only to be used on a level surface. It is adjustable in length and width. Appropriate drainage openings for integrating the drainage technology are to be created using a jigsaw (see installation instructions).
  • It is generally recommended to install the elements using wedi 320 tile adhesive, and to stick them to each other using the wedi 610 adhesive sealant (see installation instructions).
