Auger Boring

At Capitol Tunneling, we specialize in both hard rock and soft ground boring. Our fleet of 13 boring machines, ranging in size from 24-inch to 84-inch diameter, enables us to drill and install casings anywhere from an 8-inch diameter hole to a 96-diameter hole. We have more than 8,000 linear feet of auger ranging from 8-inch diameter up to 78-inch diameter, to help facilitate your auger boring needs. If we don’t have what you need, that is not a problem; we have the ability to acquire it or build it ourselves.

The latest addition to our fleet is the 84” Michael Byrne Auger boring machine. This monster is the largest built Auger Boring Machine known to the industry. With its impressive 2.2 million lbs. of thrust, powered by a Caterpillar C-9 engine producing 325 horsepower, we now have the capability of boring 96” diameter steel casing. With a combined total weight of 60,620 lbs., this 72-84” machine is guaranteed to not only turn auger, but to turn heads as well.

In addition to numerous Auger Boring Machines and the miles of readily available auger, we also maintain one of the largest assortments of auger cutting heads in the country. We own cutter heads from a variety of quality manufacturers including Michael Byrne Manufacture, Barbco, American Augers, and the Robbins Company. Our pride and joy is the hard rock disc cutting heads that we have in our arsenal that range from 24” to 74” in diameter. These specialized heads, capable of cutting granite rock up to 35,000 psi, are readily available for use on any project in the United States. We pride ourselves on being known throughout the industry for completing difficult hard rock bores on critical lines and grades. Our specialized crews have installed more than 750,000 feet of pipe ranging from 8 inches to 78 inches in diameter, using a combination of auger boring and pipe jacking methods, installing each casing on line….on grade…and on time.
