Point drainage in suspended timber floors (integrated) - Fundo Ligno

Floor-level shower systems

The wedi Fundo Ligno floor element was specially developed for use in old and new builds with suspended timber floors. With the integrated version shown here, the seal is created on the neighbouring timber construction using the wedi Fundo sealing set.

Step 1Cut out the timber beam position in the Fundo Ligno shape and remove the insulating material underneath.

Step 2Then, make a holder for the Fundo Ligno element. To do this, screw timber strips onto the available beam construc-

Step 3Build formwork (35 x 35 cm) in the drain pot area.

Step 4

Step 5Now, connect the drain pot and attach the structure preservation cover. Create the holder for the Ligno element using timber boards, which are screwed onto the strips.

Step 6Check the drain position of the wedi Fundo Ligno element and adapt it, if necessary.

Step 7Fill the recess with earth-moist screed.

Step 8Insert the O-ring int the plastic frame`s groove from above and screw down the shower tray`s screw valve using sealing insert.

Step 9Apply tile adhesive all over the underside of the shower element.

Step 10Weight the element down for 24 hours.

Step 11Seal the joins and timber beam transitions with the wedi Fundo sealing set. Recommendation: Seal the complete timber floor area with wedi Dry & Flex.

Step 12Bring the drain frame to the height of the top tile edge and secure in the bed of adhesive. If the tile is thicker than 15 mm, use the ramping element to adjust the height.
