Why is compaction of bedding and backfill materials essential when installing underground storage tanks?

Compaction of bedding and backfill materials during the installation of underground storage tanks is crucial for ensuring the stability and longevity of the tank. Properly compacted materials provide essential support that prevents movement or settlement of the tank over time. If the ground surrounding the tank is not adequately compacted, it could lead to uneven support, causing the tank to shift or sink, which can create significant operational issues or even catastrophic failures, such as leaks or ruptures.

By ensuring that the bedding and backfill materials are compacted, operators can improve load distribution and enhance the structural integrity of the installation. This aspect is vital for maintaining the tank's position and preventing potential risks associated with tank displacement caused by soil shifts or settling.

While other factors might also contribute to the overall integrity and functionality of the installation, such as aesthetics or weight reduction, the primary concern when it comes to compaction is to provide solid, stable support for the tank, making it less susceptible to external forces and ensuring proper operation over its lifespan.
