Ameri-Dome Bonus Pac - Essentials for Care & Storage
A pool dome can work even when your pool has limited concrete deck space, an above-ground design, steps, pavers, or another unusual footprint.
A ballast-based option when a standard cable-and-anchor installation is not suitable.
If a standard cable-and-anchor system is not suitable for your pool deck, we can make your dome with a water-tube ballast system.
The water tubes hold the perimeter down, while tethers prevent the dome from shifting across the deck or toward the pool.
A vinyl sleeve is built into the outside of the dome directly above each water tube. The sleeve accepts a 4- or 5-foot length of 1″ or 1-1/4″ diameter PVC pipe, available from most home improvement stores. The tie-down points connect to this pipe using one of the 3 anchoring methods below.

This type of dome can also be anchored to secure fences, posts, etc.
Typical spacing on anchor points for water tube domes should be no less than 5′ apart.
Pricing note: Water-tube domes have a 10% upcharge on the cost of the dome.
If Pool Cover Anchor Adapters (method 1) or Eyebolts with Concrete Anchors (method 2) are required, there is an additional charge.
Purchaser is responsible for providing the tie-down ropes, PVC pipe, and any anchoring stakes required, as we do not carry them.

For a wooden deck installation, the deck must completely surround the pool. The dome is mounted to the deck using a threaded eyebolt system. These anchors are spaced approximately every 3 feet to provide an even “pull” on the dome for strength and also to prevent wrinkles on the walls of the pool dome. An additional piece of vinyl is mounted to the deck at the water's edge and hangs down into the water in order to help create a proper air seal. Normally, a piece of indoor/outdoor carpet is provided by the customer to lay on top of the deck to prevent air leakage through the gaps in the wooden deck. When the pool dome is removed for the summer, the eyebolts are also removed, leaving the deck free & clear of any obstructions.
To install a dome on the ground, pouring a concrete foundation is a good method to consider. The concrete “footing” can be poured “flush” with the ground so when the dome and anchor bolts are removed in the “off” season, the area around the pool is left unobstructed. The anchor bolts are positioned every 3 feet or so in this application. Extra area can be provided within the dome to allow for patio furniture and other items. This makes sense when small children are being supervised within the unit, as the parent or other responsible individual can remain close at hand in order to monitor the use of the pool. For further specifications, see our Dome Footing Diagram.
For areas that have grass, pavers, or dirt and in situations where pouring a full footing is not desired, the use of concrete piers poured directly in the ground is another idea to think about. This method is also used for in-ground pool dome installations where the deck of the pool is irregularly shaped and the wall(s) of the dome must “traverse” over a non-concrete area. The tubing is 1″ EMT Conduit available at your local building supply store. The dome is secured to the EMT conduit at approximately 3′ intervals. Special Anchors are required, and the poured-in-place concrete block spacing can be up to 6′. For more information on this type of installation, view our Paver Details.
If the dome perimeter must cross steps in your pool deck, we can help plan an installation that follows the change in elevation. Call us at 1-800-982-6966 to discuss the layout.
A cable-bridge system can support a dome where part of its perimeter must span the water.
This mounting system allows us to place a dome over pools where spanning the water is necessary. It uses a cable system, turnbuckles, an oversize air-flap seal, carabiners, adjustable ballast containers, and UV-protective holders. See the commercial Cable Bridge mounting system (PDF) for another version of this approach.
