Stability

Reef Ballstm are designed so that over half of the weight is in the bottom near the sea floor. All sizes of Reef Balls have withstood, without movement, heavy tropical storms in as little as 20 feet of water without anchors. Reef Balls are stable because the opening in the top of the unit breaks up the lifting force of the hydrofoil effect common to dome shapes. Side holes are wider near the center of the walls and narrow near the units surface. This feature creates miniature vortexes which further reduce lifting forces and bring rich nutrients to life on the reef. Reef Balls can be cast up to double the standard weight to accommodate high energy zones, or they can be cast at 75% of the standard weight to save concrete for bay, deep or protected water locations. Our staff will help you determine the best way to insure stability.
