Soil-Freezing Pipes

More than liquid nitrogen piping systems.

Strengthening the soil for your construction project will most likely involve freezing the ground with liquid nitrogen. This is done through a series of pipes that run the brine or liquid nitrogen through the area in a continuous loop, and Pittsburgh Pipe supplies the piping you need to get the job done.

What Are Soil-Freezing Pipes?

Ground-freezing/soil-freezing pipes have been used in construction for more than 100 years for soil stabilization, to cut off groundwater, and to support excavation in unstable soils.

Small diameter freeze pipes are installed in the ground, usually vertically in a grid configuration. As a coolant, such as brine or liquid nitrogen, is pumped in a continuous loop into the grid, water in the surrounding soil begins to freeze and eventually forms a wall. The resulting soil wall is roughly the strength of concrete.

One of the main uses of ground freezing is in deep shaft excavation. It is also used extensively in mining, foundation excavation, and pump station construction, as well as environmental remediation and groundwater cutoff. Its best use is for projects where excavation support and groundwater cutoff are required, especially for deep and large excavations.

Pipe Experts

Pittsburgh Pipe provides carbon steel pipe fittings and aluminum pipes and fittings for soil freezing. We can provide seamless or welded pipes in single random lengths, double random lengths and custom lengths. End caps are normally shipped to the job site separately, as are HDPE coils and loops.

As a manufacturer, distributor, and fabricator of steel pipes and as a distributor of HDPE pipe, we provide virtually all possible diameter, wall thickness, SDR ratings, and length configurations you require.
