Pipe Ramming

For the installation of drainage pipes or the replacement of failed culverts, GM Contracting utilizes the pipe ramming process. During pipe ramming a new pipe or casing is physically rammed through the ground with a large pneumatic hammer. Pipes up to 36 inches in diameter can be rammed in lengths up to 150 feet. Once the casing reaches its destination, the soil is cleaned out of the inside and the pipe is ready for use without disturbing the surface of the road or in some cases railroad tracks. Pipe ramming can be used in vertical and angled applications in addition to standard horizontal applications.

In many cases, pipe ramming is the preferred choice over other casing installation methods because of its ability to prevent the surface from sloping or dropping during installation. This is of extreme importance for installations under highways or rail lines.
