Abstract: The present invention comprises a series of interconnectable polyethylene plastic members, which can be interlocked together to form a tank base system sized to provide a load-bearing support for an aboveground storage tank and configured to reduce rusting and corrosion of the tank from ground moisture, chemicals, and so forth wherein the interconnectable polyethylene plastic members are generally pie piece shaped and modular such that when assembled a generally circular base is formed of light weight and sturdy support members that are generally non-corrosive, chemical resistant, tolerant to temperature variations, and non-absorbing.
