What is the purpose of the hold-down pad beneath a tank?

The purpose of the hold-down pad beneath a tank is primarily to hold the tank in place. This ensures that the tank remains stable and secure, particularly in the event of environmental factors such as soil movement or seismic activity. By anchoring the tank firmly to the ground, the hold-down pad helps prevent any shifting or tilting that could lead to stress on the tank structure or connections. This is crucial for maintaining the integrity of the tank over time and minimizing the risk of leaks or spills that could occur if the tank were to move.

While stability is a related concept, the primary function of the hold-down pad is to ensure that the tank stays in a designated position, reducing the likelihood of displacement or damage. Thus, the hold-down pad is an essential component in the installation of underground storage tanks to promote safety and operational effectiveness.
