GRUNDOMAT 130 Servo Underground Piercing Tool The GRUNDOMAT 130 Servo is a heavy-duty 5 in. pneumatic boring missile designed for trenchless installation of pipes, cables, conduit, and utility lines. Powered by compressed air, this cylindrical air-hammer drives through the ground to create a clean underground bore without open-cut trenching. This missile bore solution is ideal for larger underground crossings under roads, driveways, sidewalks, parking lots, landscaped areas, and other surface structures where reducing surface disruption is important. As a pneumatic mole, the GRUNDOMAT 130 Servo is suitable for displaceable soils such as sand, loam, and gravel, including soil conditions with fracturable rocks. This boring mole is not designed for solid rock or unfracturable rocks, and very soft soils may affect accuracy because the tool’s own weight can cause it to deviate.
