Grundomat 100PK (4 in.) Basic Package

The GRUNDOMAT 100 PK is a compact 4 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 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 100 PK 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.
