Foundation: Forming, Spacing & Setting
Forming the Foundation
The wall installation is very similar to the concrete/ substrate installation without the forming process. The dimensional requirements for installation will be the same.
The lip of the waterfall must be fully supported by the poured substrate (usually gunite or concrete).
It is recommended that steel rebar be used to further support the waterfall inside the substrate.
When forming the area for installation, note that plumbing and electrical notches must be provided
Inlet Spacing
Waterfall Lip Overhang
The waterfall must be installed with a minimum of 1/8” overhang from the finished surface.
Mortar or thin-set should be used to secure the waterfall in place.
Setting the Waterfall
For standard pool applications, the waterfall must be installed before the deck and coping.
Place the waterfall in the notches cut in the bond beam or wall application.
Utilize substrate material such as tile, thin-set or mortar to make sure that the waterfall is level with the top of the upper edge of the bond beam.
Fill the gaps around the unit with concrete or similar material in preparation for the tiles or other material.
Cut the tile/material to fit under the lip of the waterfall using thin-set or similar substance to secure in place.
Ensure the waterfall is level front to back and across the length of the fall.
Complete the electrical installation and plumbing before covering the top deck.
Access Door Install
Glue door covers to the cuttable door using PVC glue.
OPTIONAL: The opening of the cuttable door can also be filled with grout, plaster, caulk, etc. to match the pool wall.
When installing the final fascia to the wall whether using tile, stone or other substrate, do not cover the access doors.
Fill only the opening of the cuttable door, do not cover the latch hole.
These will be required for servicing the unit.
