Taking precautions
The elevated perimeter overflow “splash pad” was floated with a leveling bed of mortar. After curing, it was coated with a waterproof membrane and crack control fabric.
To prevent water wicking and to control efflorescence both sides of the vanishing edge wall were waterproofed. The waterproofing was wrapped onto the spa, throughout the hidden gutters and collection basins. It was then coated with a compatible thinset to provide protection from abrasion and wear.
The thinset also created a surface for areas that were to later receive Pebble Sheen. In the background, the spa has been floated and leveled and is about to receive waterproofing. A shade structure is being erected over the splash pad to protect the glass tile that is to be set in this area.
