The trust of our clients is an incentive for future projects.

Range of Services
We plan tunnels, shaft constructions and caverns in rock and loose rocks, in open and in mining technique. Experienced in conventional and mechanical driving, we realise underground facilities of all dimensions: for subways and railways, for road transport, for energy supply and telecommunications as well as for municipal or regional supply and disposal tasks.

Competence & Experience
With many years of experience, we are designing special constructional measures such as injections for building safety or ground water table lowering in order to improve execution reliability and driving performance. With ground freezing technology and other special construction methods, we also master difficult ground conditions in groundwater or in confined urban areas.
