Utilizing the latest technology and equipment, the Nix team always meets the challenge with a commitment to doing the job right the first time, every time. We specialize in solving complex underground problems with meticulous planning and precision execution.
Jack and Bore is a method employing a machine that simultaneously jacks pipe into the ground using hydraulic rams and augers out the soil to install the new pipe.
It combines pipe jacking with a laser-guided, steerable tunnel bore machine (TBM). Hydraulic cylinders push specially designed jacking pipes or steel casings through the ground behind the TBM, which is manned by an operator who observes soil conditions and to monitors line and grade to ensure a precise installation.
Ideal for projects requiring pinpoint accuracy on line and grade, Guided Auger Boring
is a highly specialized technique. Pilot tubes establish line and grade, then the new casing is jacked into place while simultaneously removing the soil. It provides exacting installation of a variety of casings and applications while not intruding on activities in the area above ground.
This method can be either guided or unguided depending on the level of accuracy required. Guided pipe ramming combines pilot tubes, a reaming head and a pipe hammer to establish accurate line and grade throughout the drive. Ideal for use in a variety of soil conditions and with an array of materials, this proves an economical alternative to other trenchless applications.
The new pipe is then directly jacked behind the pilot tubes. Avoiding long, open trenches means minimal intrusion to the area above ground. This method proves useful for projects with limited clearance and those that require pinpoint accuracy.
This method typically involves large-scale excavation, but is ideal when ground conditions are stable and the utility to be installed is relatively shallow or in areas without other utilities in close proximity.

A bursting head moves along the path of the old pipe, while simultaneously being followed by the new line. The head breaks apart the old pipe, sending the remnants into the surrounding soil, paving the way for the improved utility. By eliminating the cost of relocating the utility while reducing the above-ground intrusion, pipe bursting is a versatile method for replacing a variety of pipelines.
This technique involves running a smaller diameter pipe inside the existing host pipe, then filling the void between the two pipelines. Best when used along a relatively straight line, slip lining is an economical approach to replacing an inferior pipeline along its existing path.
