Typical Applications: Placement of steel casing under geographic features such as freeways, canals and railroad tracks to carry water lines, sewer lines, irrigation lines, etc.

Description: Pipe ramming is a two-stage technique for installing steel casings from a bore pit to a reception pit utilizing dynamic energy from a percussion hammer attached to the end of the pipe. A pneumatic device or “pig” is then used to push the spoils into the reception pit.

Limitations: Pipe diameters range from 6” in diameter and up, and with no limit on linear feet.

Considerations:

	Works best in sandy, rocky soils
	Fast, effective clean out
	Several methods available
	Unable to guarantee line and grade of casing
