Going new paths is always more difficult than following existing ones. 


The reinvention for boring small diameters in soils and granulates

Our goal has always been to revolutionise trenchless tunnelling and transform it into a sustainable, electric and smart technology. But our technology is not only relevant for trenchless tunnelling for small diameters - it is especially suitable for granular crossings and sandy soils. It has never been easier and more efficient to cross the underground/ granulate.
