Soil Stabilization For Oil & Gas Pipelines
For any oil and gas project, it’s essential that the earth both above and below the construction area can easily bear a heavy load without shifting or crumbling which can both damage the construction facility and pipe.
But what can be done when the natural earth from which the trench is dug is from weak or unstable soil? In these cases, it must be stabilized using mechanical, chemical, or polymer-based approaches, which render it usable for the construction project. Melgaard Construction specializes in soil stabilization for oil and gas construction throughout Wyoming, Montana, and North Dakota, ensuring construction integrity for decades.
Mechanical stabilization takes place when heavy equipment is used to physically compact the soil to the desired density. This is a very effective, although time-consuming method, and is one we still widely use today.
Adding compounds to the soil that react to changes its properties is another standard method of stabilization and has the benefit of being a much faster and more efficient way to stabilize large areas; although because it changes the properties of the soil, it’s not ideal for every situation.
Typical additives include lime and fly ash combined with soil cement. Lime and fly ash are especially effective at treating soils with large concentrations of clay or sand.
The newest form of stabilization, polymer-based compounds, are more cost-effective, efficient, and environmentally-friendly than most chemical agents and are often the stabilizers of choice, either on their own or in addition to mechanical stabilization.
Why Soil Stabilization
With soil stabilization, the weight-bearing capacity of the soil is significantly increased, and the additional load of the traffic can be borne without the underlying earth shifting, which can damage the construction. Stabilized soils are also less permeable, and thus less likely to absorb water that will freeze the ground and cause problems with expansion and frost heave. Melgaard Construction employs all methods of stabilization, selecting the best way or combination of methods per the needs of the construction, surrounding environment, and human activity expected around the construction area.
