Wind-resistant variant

Armor Ball® AQUA — the 75 MPH water-ballasted ball cover

Armor Ball® AQUA water-ballasted covers on a large lined pond in an open, wind-exposed setting.

The physics

Mass from the water itself

Cross-section view at the waterline showing Armor Ball® covers floating low on their pre-filled, sealed water ballast.
Waterline cross-section: each ball rides low and heavy on its pre-filled, sealed water ballast.

Pre-filled, sealed ballast

Each ball arrives pre-filled with sealed water ballast — ~275 g versus a ~50 g shell — anchoring the cover against wind. Sealed at the factory, the ballast never mixes with the liquid you're covering.

Holds to 75 MPH

The added mass raises wind resistance to 75 MPH (120 km/h) — more than double the 35 MPH standard rating.

No liner penetration

No pumps, anchors, cables, or penetrations — nothing to engineer into the basin or maintain over time.

Fast to deploy

Ships in ~40 lb mesh bags; a 53-ft dry van unloads in about 1–2 hours.

Demonstration: Armor Ball® AQUA 275 holding position in 200+ MPH test wind. Rated wind resistance is 75 MPH per AWTT published data.

Site assessment

Is your site too exposed for a standard ball cover?

If sustained winds regularly exceed 35 MPH, AQUA's water ballast keeps the cover in place. Tell us your location and exposure and we'll recommend the right cover.

FAQ

Armor Ball® AQUA questions, answered

What makes Armor Ball® AQUA wind-resistant?

Each Armor Ball® AQUA comes pre-filled with sealed water ballast, so the ball weighs roughly 275 g versus about 50 g for the shell alone. That added mass raises wind resistance to 75 MPH (120 km/h) without pumps, anchors, cables, or liner penetration.

How is Armor Ball® AQUA different from standard Armor Ball®?

AQUA shares the same 100 mm UV-stabilized HDPE ball, 91% coverage, pH 2–13 resistance, and tool-free install, but adds pre-filled, factory-sealed water ballast that raises wind resistance from 35 MPH to 75 MPH. Buoyancy is about 5 lb/ft² water-ballasted and heating-cost reduction is up to ~75%.

Do I need pumps or anchors to ballast Armor Ball® AQUA?

No. The ballast is water sealed inside each ball at the factory, so there is nothing to fill, pump, or anchor in the field — and the ballast never mixes with the liquid you are covering. There are no pumps, anchors, cables, or liner penetrations to engineer, install, or maintain.

How is Armor Ball® AQUA shipped and unloaded?

Armor Ball® AQUA ships in roughly 40 lb mesh bags; a full 53-ft dry van unloads in about 1–2 hours.

Is my site too exposed for standard Armor Ball®?

Standard Armor Ball® is rated for 35 MPH winds. If your site regularly exceeds that, step up to Armor Ball® AQUA (75 MPH). For even higher exposure, AWTT offers Hexprotect® AQUA / Rhombo Hexoshield® up to 130+ MPH.
