spas. The reinforcing rod or mesh in
the pad should be attached to a bond wire.
• Concrete sloped at 1/2 inch per 10 feet is preferred so that
rain water and water spillover will run off and not puddle
underneath the spa (water under the spa for long periods of
time may cause the wood to deteriorate).
• If stepping stones or railroad ties are selected for the spa
foundation, they should be placed and leveled below the
entire spa to maintain even distribution of the spa weight.
• It is important to note that soft surfaces, even when stepping
stones are used to distribute the weight of the spa as evenly
as possible, will still have a tendency to settle unevenly,
resulting in an unlevel spa.
• Remember, placing the spa on grass or dirt may increase the
amount of debris which is inadvertently brought into the spa
water on the user’s feet.
If you are purchasing a deck package or a spa enclosure with your spa,
a solid foundation becomes mandatory. Placing them on any surface
other than a single level pad could create problems with their installation.
Pictured at right are a few of the recommended surfaces.
As a homeowner, it is your responsibility to provide a suitable, level
foundation for your spa. Keep in mind that most delivery crews are not
equipped to level and prepare spa sites.
If you are interested in having a concrete slab, brick surface, or wood
deck installed, your Caldera
dealer should be able to suggest a qualified,
licensed contractor.
DELIVERY ACCESS
First, locate the dimensions of your spa on the chart that is found on the
next page. The dimensions shown are the measurements of the spa in
the vertical position, laid on its side.
Next, contact your dealer to find the height and width added by the
delivery cart which the dealer will use to deliver your new spa. Use
the height of the cart plus the dimension shown as H to determine the
vertical clearance required to pass the spa and cart. Use the width of the
cart, or dimension W, whichever is greater, to determine the maximum width of clearance necessary.
NOTE: It may be necessary to allow for additional over-head clearance if the spa will be rolled up or down an incline
or moved up or down a short flight of stairs.
Use the information in the picture below to determine the requirements for access to your desired location. It may be
necessary to remove a gate, part of a fence, or other movable obstructions in order to roll the spa to its installation
site. About ten percent of the time, a crane is the only way to install the spa by lifting it to its final destination.
If the spa has to be taken off of the cart to go over a wall (either because the entry area is too narrow, the eaves are
too low, the corner is too tight, or the stairway is too steep), a crane will be required. Don’t be alarmed!
