Which soil conditions are best for burying a propane tank?

Soil Density and Water Table Requirements

When burying a propane tank, the primary concern is preventing water from accumulating around the tank. Soils with a low water table and high density are ideal. A water table that’s too close to the surface can lead to water seepage into the tank, causing corrosion and potentially catastrophic failures. Soil density also plays a crucial role, as loose or sandy soils can allow water to flow freely, while denser soils like clay can help prevent water infiltration.

Ideal Soil Classifications and Depth Requirements

Propane tanks can be buried in a variety of soils, but the best candidates include compacted clay, silty clay, or sandy loams. These soils are more resistant to settling and have lower permeability rates, reducing the risk of water accumulation. When burying a propane tank, the minimum recommended depth is 12 inches of undisturbed soil, which helps prevent potential soil settling and water infiltration. Additionally, it’s essential to ensure the top of the tank is at least 18 inches below grade to prevent damage from equipment or other external factors.

Proper Burying Techniques and Tank Orientation

To ensure a safe and successful propane tank burial, it’s essential to follow proper techniques. The tank should be oriented with the valve facing upwards and the dip tube protruding from the top. When burying the tank, it’s crucial to use a backhoe or similar equipment to minimize soil disturbance and prevent potential damage to the tank. A 2-foot wide by 2-foot deep trench should be dug around the tank, with a minimum of 12 inches of undisturbed soil on top of the tank. This will provide a stable and secure environment for the propane tank.
