Soil Displacement Technique
Horizontal Boring with Grundomat®
For nearly 45 years, Grundomat pneumatic piercing tools have provided precise horizontal boring capabilities beneath roads, railways, and various landscapes throughout North America and beyond. Several industries, including those focused on water, gas, sewer, and electrical utilities, have significantly benefited from this dependable trenchless technology. Requiring minimal operating space, Grundomat tools offer a cost-effective alternative to more significant and more costly directional drilling equipment in numerous cases.
Grundomat can achieve accurate horizontal bores ranging from 50 to 150 feet in length. These versatile pneumatic tools function effectively in all displaceable soils, encompassing sand, loam, and even gravel, and can be easily configured to accommodate a broad spectrum of new pipe materials.

The Grundomat tool possesses the capability of executing precise horizontal bores across distances that span from 50 to 150 feet. This pneumatic piercing instrument proves effective in a variety of displaceable soil types, which include sand, loam, and gravel. Furthermore, it can be readily adapted to facilitate the installation of a diverse array of new pipe materials.

In the piercing tool, compressed air drives the piston repeatedly against the rear of the chisel head assembly. This action compresses The pre-tensioned steel spring and propels the chisel head forward independently of the main casing, thereby facilitating the creation of a pilot bore. This continuous force subsequently advances the main casing. With decades ofity, the Grundomat's patented stepped-cone head consistently delivers accurate results.

Conventional fixed-head piercing tools often veer off course when encountering tough soils or obstacles, following the path of least resistance and leading to failed bores. In contrast, the Grundomat piercing tool features a distinctive reciprocating stepped-cone chisel head that effectively penetrates solid obstructions. This two-stroke mechanism directs the piston’s impact onto the mobile tool head, guaranteeing optimal trenchless dull performance, even in arduous conditions.
At FIBCO, we employ the advanced Grundomat pneumatic piercing tool as an integral component of our trenchless technology solutions to optimise Fibre-to-the-Premises (FTTP) network installations for the National Broadband Network (NBN). The Grundomat's design facilitates enhanced target accuracy compared to conventional tools, permitting the simultaneous execution of bores and pipe installations in a singular, efficient process. This approach significantly decreases surface disruption affecting traffic, buildings, and utilities, thereby markedly reducing the necessity for expensive restoration typically associated with older trenching methodologies.
Featuring a patented reciprocating stepped-cone chisel head and a user-friendly reverse mechanism, the Grundomat enables rapid and precise operations, ensuring expedited project completion timelines with minimal crew requirements. Additionally, the tool’s robust construction translates to reduced maintenance demands, thus allowing FIBCO to provide prompt, cost-effective, and dependable network installations, all while preventing extensive surface damage and ensuring minimal disruption to the surrounding environment.
