What is the major cause of deflection in a newly-installed tank?

Improper bedding is a significant cause of deflection in a newly-installed tank because the bedding material directly impacts the tank's ability to support its weight and maintain its structural integrity. When a tank is installed, it should be placed on a stable and level bedding material to distribute the load evenly. If the bedding is not adequate—whether it's inconsistent in density, improperly compacted, or insufficient in size—the tank may settle unevenly or shift, which can lead to deflection.

Additionally, this issue is compounded if the bedding does not allow for adequate drainage or if it becomes saturated, as waterlogged bedding can become compressible, exacerbating the deflection problem. Proper bedding is essential for maintaining the tank's position and load-bearing capacity over time, which highlights its role in preventing structural damage and ensuring the tank operates safely and effectively.
