For decades, traditional auger drilling techniques have been used to install pipes under roads and railways using hydraulic rams and auger drills. In recent years, these drillings can also be controlled, with a pilot bore first. Positioning is determined by means of a laser.
For auger drilling, a pressure chamber is required to position the machine at the desired installation level and a (small) receiving chamber on the receiving end to receive the drilling fluid. Auger drilling is normally performed above the groundwater level. If groundwater is present, the groundwater level can be temporarily lowered or a water trap can be applied.
Auger drilling technology can be used to install pipes made of steel, concrete, stoneware, GRP, GRE, PVC, and HDPE. These pipes can serve as sheathing for cables and conduits, or directly as a medium-carrying pipe for process water, for example.
We have specialized in auger drilling since 1980 and therefore have extensive experience. For auger drilling, we have five pilot-controlled auger drilling rigs capable of drilling diameters up to 1,720 mm.
With this extensive fleet of machines, we have the most efficient machine available for every project and we can even deploy multiple machines simultaneously on a project.
For crossing the Dutch railways, we have the ProRail certificate S-D(A), S-D(B), S-D(C) and S-D(D), which allows us to carry out boreholes up to 5 metres in diameter.
