GRUNDORAM® Pneumatic Pipe Ramming

Pipe Ramming With Grundoram®

Whatever direction your work takes you, Grundoram can handle it . . . from conventional horizontal pipe ramming to vertical pile driving. The Grundoram pneumatic pipe ramming tool is used for the trenchless installation of steel pipe through a wide variety of soil types, without any rise or fall in the ground’s surface. Some trenchless casing installation methods are impaired or even rendered inoperable by rock or boulder filled soils. During the pipe ramming process however, boulders and rocks as large as the casing itself are “swallowed up” as the casing moves through.

Trenchless Casing Installation through Pneumatic Pipe Rammer

Pipe ramming for horizontal, vertical, and angled installation of steel pipes or casings. Additionally the Grundoram can be used to assist or salvage directional drilling operations.

Pipe Ramming Overview

The Grundoram pneumatic pipe rammer attaches to the back of steel pipes or casings and hammers them into the ground. Pipe can be driven as one continuous run or in sections depending on the space available at the insertion site. As the pipe rammer pushes the pipe or casing through the soil, rocks and other obstacles are “swallowed up.” Spoil is removed by using compressed air and/or water, augers, or skid steers on larger diameter casings.

Trenchless Technology Benefits

Grundoram is completely self-contained for fast, efficient, and safer installations of steel casings.
Faster installation of large pipe without ground slumping
Works equally well in confined & ample work areas
Swallows rock up to the diameter of the new casement
Minimal disruption to traffic, buildings, and other utilities
Avoids sizable surface damage and costly restoration required for old trenching methods
Accelerated project completion timeline
Easy to set up and operate

Grundoram® Features

Grundoram models are available for a variety of applications and are proven effective in the toughest conditions.
Each pipe ramming tool is adaptable to several casing diameters
Unlike other pipe ramming tools, each Grundoram tool head and casing is made from a solid block of alloy steel for optimum strength and durability
Anti-corrosive construction
Minimal maintenance
Long service life

Typical Set-up

Pneumatic pipe ramming set-up

Pipe Clean-out is Fast, Effective

Pipe clean-out with pipe ramming requires minimal additional equipment. In fact, the air compressor used to power the Grundoram is used to expel the spoils. Once a seal-off plate is installed on one end of the casing, air pressure builds inside the casing and forces the spoils out. As with any process using compressed air, extreme caution should always be used to keep workers away from the exit area.

Augers Work, Too

Larger casings clean-out works especially well with augers. This is good news for contractors that already own this type of equipment.
