The company KARL WEISS Technologies operates in the field of trenchless construction for pipelines. We also execute infrastructure services in civil engineering underground, as well as the classic building of pipelines and sewers. Alongside project steering, including large-scale civil and underground engineering and city pipeline building projects, we also plan projects, as well as developing new trenchless technologies for building sewers and pressurized pipelines. Over 110 years of thinking and acting in a progressive entrepreneurial spirit have turned the construction firm KARL WEISS into a high performance, technology-oriented business group. We work out intelligent alternative proposals for civil engineering underground and order our machines to be custom-built for the purpose. In the meantime, many of our worldwide patented processes in trenchless pipeline building have gained recognition beyond the borders of Berlin and Germany. Currently we are active and successful in marketing our own products and expertise in Europe and the USA. We are PARTNERING partners of the Berliner Wasserbetriebe, Berlin's water utility company. Our firm is certified as a vocational training centre in accordance with the German standard, DIN EN ISO 9001:2008.
