The boring machines have clearly demonstrated their superiority over open trench construction with regard to technical, economical and ecological aspects. More than 1 Mio. m performed by Bohrtec auger boring machines have proved this fact.
All compact machines can be operated guided or unguided. Compared to the conventional microtunneling machines the guided auger boring machines are very cost-effective and simple to use and have been steadily developed by Bohrtec over the last 30 years. Today these machines can be used in almost all ground conditions and under ground-water.
Different drilling heads for different ground conditions and diameters, Front Steer for drilling in non-displaceable soil and rock and the Hole Opener for precise installation of plastic pipes are available.
