The GBM 240A is the industry-leading pilot tube system for accurately guiding horizontal auger bore equipment. With hundreds of systems being used globally, industry leaders rely on the accuracy and versatility that the 240A adds to their trenchless toolbox.
Features:
- Establish line and grade accuracy critical for gravity flow installations.
- Adjustable base frame adapter fits all major auger bore machines.
- Minimize project cost by reduced casing diameter requirements.
- Achieve longer auger bore installations with straight alignments.
- Avoid tripping augers to survey alignment and adjust for deviations during standard boring.
- Probe for obstructions or detail changing ground conditions along the alignment during the pilot tube installation.
- Utilize for several other trenchless installations such as guided pipe ramming, guided reaming, probing, pipe roofing, foundation securing, geothermal, etc.
- Utilize as a stand-alone system in a 10-ft shaft to direct install product pipe up to 24in OD.
- Installs pilot tubes in a wide range of ground conditions including rock.

Testimonials
I have used TBM equipment since 1996 for the installing pipes from 1.22 m to 2.44 m of internal diameter, they are very efficient in clays and silts with a high content of humidity.
I have also used GBM systems for driving smaller diameters in soils soft from the Valley of Mexico and are suitable for these conditions.
