Missiles

Grundomat® line of pneumatic piercing tools can perform accurate horizontal bores from 50’ to 150’.  The Grundomat can be used in all displaceable soils:  sand, loam & even gravel and is easily configured to pull in a wide variety of new pipe materials. 

The Grundomat® Advantage
Grundomat pneumatic piercing tools have been providing accurate horizontal bores beneath roads, railways, and landscaping across North America and around the world for nearly 40 years. Water, gas, sewer and electrical industries have all benefited from this work horse of trenchless technology. Minimal operating space is required and the tool serves as a complement, and in many situations an economical alternative to, larger, more expensive directional drilling equipment.

What it Does
Grundomat can perform accurate horizontal bores from 50 to 150 feet in length. The Grundomat can be used in all displaceable soils: sand, loam and even gravel and is easily configured to pull in a wide variety of new pipe materials.

How it Works
Compressed air repeatedly propels the piston against the rear of the chisel head assembly. This first compresses the pre-tensioned steel spring which forces the chisel head assembly forward independently of the main casing to provide a pilot bore. Then, the same continuous force thrusts the main casing ahead. With decades of proven performance, the Grundomat’s patented stepped-cone head consistently provides accurate results.

Models Available
Sixteen models are available from 1 ¾ inches to 7 inches in diameter that accommodate most project needs.
