What is the minimum thickness of bedding material when using a bottom hold-down pad under a steel tank?

The minimum thickness of bedding material when using a bottom hold-down pad under a steel tank is 8 inches. This standard is established to ensure proper support and stability for the tank under various conditions, including weight distribution and environmental factors.

An 8-inch layer of bedding material plays a crucial role in providing a solid foundation that can help prevent settling or shifting over time, which is especially important for maintaining the structural integrity of the tank and avoiding potential leaks. Adequate bedding material thickness also helps in accommodating any potential ground movement or changes in the substrate, thus supporting the overall safety and longevity of the installation.

It is important to adhere to established guidelines and regulations regarding thickness to prevent failures that could lead to costly repairs or environmental concerns.
