Making the Right Choice: Static vs. Pneumatic Pipe Bursting for Long Island’s Unique Underground Challenges

When Long Island property owners face deteriorating underground pipes, choosing the right pipe bursting method can mean the difference between a successful, cost-effective repair and a problematic project. Engineers should compare both pneumatic and static/hydraulic pipe bursting techniques to determine which method is the best choice for their project, and the choice to use one over the other may concern soil conditions, or type of pipe workers are replacing.

Understanding the Two Primary Pipe Bursting Methods

There are two main ways of performing pipe bursting: pneumatic and static/hydraulic. When considering pipe bursting techniques, the pneumatic method is the most common system used. For about 80% of all pipe bursting projects, workers use a pneumatic hammer driven process.

Pneumatic pipe bursting is like pile-driving with the unit delivering compressed air strikes at 180-580 blows per minute. Pneumatic systems are driven by compressed air and break the existing pipes like a hammer putting a nail in a wall. In contrast, static pipe bursting techniques is a pull-through method. There is no mechanism to push the new line into place.

Pipe Material Considerations for Long Island Properties

The type of existing pipe material significantly influences which bursting method to use. Pipe bursting is used to replace brittle pipes such as clay, asbestos cement, concrete and cast iron by pulling through the host pipe a static or dynamic bursting head to fragment the existing pipe.

Cast iron sewer lines should be burst using the static/hydraulic method and not with pneumatic equipment. This is because this method is particularly effective when dealing with more rigid materials such as cast iron or certain types of concrete. The pneumatic force can efficiently break through these materials, allowing for the installation of a new, more durable pipe.

For other common Long Island pipe materials:

• The static pipe bursting technique is adaptable to various pipe materials, including clay, concrete, and PVC.
• PVC pipes can only be installed by static pipe bursting.
• The Grundocrack can be used to burst fracturable pipes (cast iron, clay, concrete, RCP, ABS and some plastics) with diameters between 4 and 54 inches.

Long Island Soil Conditions and Their Impact

Long Island’s unique geological conditions play a crucial role in method selection. The method displaces fragments of the existing pipe into the soil and thus is most appropriate for compressible soils. Ground conditions suitable for pipe bursting/splitting include clays, silt, generally soft cohesive material. Loose and medium sands and gravels are also feasible.

The success of static pipe bursting depends heavily on the type of soil surrounding the pipeline. Long Island’s varied soil conditions, from sandy coastal areas to clay-rich inland regions, require careful evaluation to determine the most effective approach.

In the course of time, rain shifts the soil. Pipes sink when soil under them sinks. As a result of the shifting, cracks appear. These conditions are particularly common in Long Island, where soil movement can affect pipe integrity over time.

Advantages and Limitations of Each Method

Static pipe bursting offers several advantages:

• Unlike traditional methods that require large trenches, static pipe bursting only requires small launch and reception pits. This reduces disruption to roadways, sidewalks, and landscapes, making it ideal for urban areas or environments with sensitive ecosystems.
• Static pipe bursting can replace old pipelines with larger-diameter pipes, improving flow capacity and future-proofing infrastructure for population growth and increased demand.
• Static pipe bursting has replaced pneumatic bursting as the most commonly used variant primarily because of the absence of shock waves generated by a dynamic burster, which can cause damage to adjacent buried utilities.

However, static pipe bursting can increase the diameter of the replacement pipe, it is usually limited to a diameter increase of up to 30%. For significant upsizing, other methods may need to be considered.

Pneumatic pipe bursting provides different benefits, particularly for certain pipe materials and conditions, but requires careful consideration of surrounding utilities due to the dynamic forces involved.
