US Cover-Depth → Load-Class Model Selector

Match the traffic over the tank and your depth of cover to an SG-series model and AASHTO live-load class — with the badge caveat plan reviewers actually check.

1. Surface & heaviest load above the tank

2. Depth of cover over the tank

Cover from finished surface to the top of the tank. Deeper compacted cover spreads the wheel load; shallow cover under traffic concentrates it.
Select your loading and cover, then press Recommend a model.
