Grading Prior to Excavation

•The spa must be properly back-filled with wet sand, underneath and on all four sides.

•The final architecture must include permanent ground coverage within a 10 feet radius of the spa.

•Never place any spa in a sealed area. Water must be able either to be absorbed into the surrounding area or channeled away. Water build- up under and/or around the spa, will cause the spa to float out of the ground.

Selection of the Designer Spas site will determine how much grading will have to be accomplished prior to the actual dig for the spa. Naturally, a level area is best because it will require the least amount of preparation for the dig, but in many cases there is no level area, therefore, the site must be prepared to accept the Spa prior to dig. The spa site should be elevated slightly higher than the surrounding area

When dealing with slopes, the severity of the slope will determine if retaining walls must be built in order to have a level area for the spa. If the slope is relatively minor, contact your local building safety.

Site Excavation – Hard Bottom

For hard bottom placement for in-ground spas, you will need a smooth and flat concrete surface at least 4” thick as large as the bottom contact points. Be sure not to seal the bottom off and making a sealed box. You will need adequate water drainage for escape under the spa. A gravel beds around the concrete base will help with this.

Site Excavation – Sand Bottom

With the spa area and all elevations planned including your decided type of decking, you are now ready to proceed with the dig. An ideal excavation is one that is as close as possible to the dimensions of the spa shell, but with the following rules in mind. The excavation should be 2” to 4” deeper than the actual spa for your sand bed. The sand bed is to level the spa shell and provide a perfect support base with no voids when the spa is lowered into the hole. Your excavation should be approximately one foot longer and one foot wider than the spa shell. This will allow for a six inch over dig all the way around the spa once it is in place. Additional hand excavation will be required to insure the skimmer will fit in the excavation when attached to the spa.

Sand or rock dust must be used to bed the shell into the excavation and for backfill. In no event is dirt to be used. One of the easiest ways to know how much sand is needed to be placed on the bottom of the excavation is to set a grade stake at all four corners, and one on each side of the center line in the bottom of the hole. If there are areas that are deeper than 2” to 4”, these can be filled with sand and are of no consequence.
