NEW GRUNDOMAT GRUNDOMAT 180 P

The GRUNDOMAT 180 P is a heavy-duty 7 in. pneumatic piercing tool — the largest in the Grundomat line — built 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.

What contractors use it for: boring under roads, railways, parking lots, and other surface structures to install water and gas lines, sewer laterals, casing, and large conduit runs — no open-cut trenching, no surface restoration. Requires a 159 CFM tow-behind compressor.

Also known as: underground mole, boring missile, air mole, ground piercing tool, horizontal boring tool, trenchless bore tool, pneumatic gopher. Whatever your crew calls it — this is the 7 in. class tool.

As a pneumatic mole, the GRUNDOMAT 180 P performs well in displaceable soils such as sand, loam, and gravel, including soil conditions with fracturable rocks. It is not designed for solid rock or unfracturable rocks, and very soft soils may affect accuracy because the tool’s own weight can cause deviation.
