    Pipe Ramming is a process where a steel pipe is installed with a pneumatic hammer. The grade can be set and controlled from the launch pit, with distances up to 150 feet possible. As the steel line is installed, the soil is forced into the interior of the pipe. Once the pipe is installed to its desired locations, the soil is removed from inside.
