Advanced Underground Pipe Installatin, Inc dose horizontal boring for various differnt types of contractors. We install sprinkler pipe, water services, sewer pipe, electrical conduit, phone and power cable underground. The machine we use is a pusher puller that is pit lonched. The machine pushes a solid steel rod from one hole to a target hole where we attach to the pipe to be installed behind an expander that is slightly larger than the O.D. of the pipe and then pull the rods and the pipe back to the launch pit. When we burst a pipe we send the rods down the old pipe to the exit hole where we attach to the pipe with a iternal pulling eye that is attached to bursting head and pull the rods and pipe back, bursting the old pipe and insalling the new HDPE Poly pipe right in the same place as the old one was.
