Pouring the Deck
It is recommended that all electrical hook ups and all plumbing be completed
before pouring the concrete. Make certain all electrical inspections on
lights, bonding and all other electrical work have been completed and
checked off by the local inspectors prior to proceeding with your concrete
or finish work. It is a good idea to run the spa for at least 24 hours before
pouring the concrete to insure there are no leaks. We understand you
want to enjoy your spa now, but a 24-hour period with your spa running will
let you know of any problems before they will be extremely hard to fix.
The type of decking you have selected will have determined the grade of
the spa. If you are pouring a regular deck up to the spas coping, then the
top of the coping should be 4” above the surrounding area. In either event,
it is recommended to dig out an area around the spa exposing the flange
of the coping and just under it. This is important, as concrete should be
packed under and over the flange of the spa, as the deck is poured. This
will lock the spa into the concrete and provide for a much stronger bond
of the spa to the deck. It will also eliminate cracking of the deck where it
meets the spa.
When setting your outside forms, remember you want any water from rain
or splash out to run off the deck, not into the spa. If your deck is going to tie
into an existing deck, than some type of drain system should be planned to
handle the run off. Proper drainage planning is very important.
An experienced concrete finisher should always be used when pouring
spa decks, especially when you are doing a cantilevered deck, as the
forms must be taken off at the proper time to allow finishing of the inside
of the form.
