Tank Solutions — Underground Tanks
FRP Underground Tank
Corrosion-resistant buried storage, a common choice for underground duty.
FRP Underground Tank
Typically a purpose-designed single- or double-wall FRP tank for compatible liquids, where burial is treated as a structural and installation condition.
Burial/traffic rating, hold-down system, monitoring, lifting, bedding and backfill are confirmed, along with UL or other listing scope where required. FRP resin compatibility must match the stored liquid.

Where It’s Used
Frequently Asked Questions
Why is FRP common for underground tanks?
It doesn't corrode in buried, damp conditions, and purpose-designed burial-rated FRP tanks are engineered for earth pressure, buoyancy and traffic loads.
Is a listing always needed?
Where the service requires it (e.g. flammable liquids), the UL or other listing scope is confirmed for the exact model.
