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, bond-
ing and all other electrical work have been completed
and checked off by the local inspectors prior to pro-
ceeding with your concrete or nish 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 under-
stand 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 x.
The type of decking you have selected will have de-
termined 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 ange of the coping and
just under it. This is important, as concrete should be
packed under and over the ange 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 ex-
isting deck, then some type of drain system should be
planned to handle the run off. Proper drainage plan-
ning is very important.
An experienced concrete nisher 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 nishing of the
inside of the form.
