What can be added to the top of a buried tank to counteract buoyancy?

The addition of weight to the top of a buried tank is a common practice to counteract buoyancy. When a tank is installed underground, there is a risk that it may float or be displaced by groundwater if it is empty or not adequately filled. This buoyancy effect occurs because water exerts an upward force on the tank, which can lead to instability and movement.

By adding weight, the downward force applied to the tank increases, effectively countering the buoyant force exerted by the surrounding water. This additional weight can be achieved using various materials, and it helps ensure the tank remains securely in place.

While bricks, concrete, or similar heavy constructions could theoretically serve the same purpose, the term "weight" encompasses a broader range of materials and methods that could be used for this specific application. Thus, the understanding of how weight functions in buoyancy is crucial for maintaining the integrity and safety of underground storage tanks.
