A plurality of modular pad units each include a rigid foam core having a polymer coating. Each unit has a similar configuration, substantially uniform thickness and a perimeter shape that includes a circular part, a male key part configured for mating with a female keyway part. The units are arranged by interlocking the units such that the male key part of each modular pad unit mates with the female keyway part of another modular pad unit, and the circular parts of the units align to form a circle. The multiple interlocked units providing a circular storage pad that is at least ten feet in diameter and that has a thickness of at least three inches. The bottom of the storage tank is placed directly on the circular storage pad to support and isolate the tank bottom from the ground at the site. |
