Deck-on-deck construction uses track channel to seamlessly integrate
the Underside™ track system on freeform pools. This type of
cover installation is also well suited for vinyl-liner or fiberglass
During pool construction an outer, slightly raised deck with a rectangular opening is placed around the pool. This allows the tracks, which must always run parallel to one another, to be laid out at the widest part of the pool. The track is hidden under the coping of the slightly raised deck and is therefore out of sight. With this technique, you can also include other features such as spas and waterfalls.
