The growing environmental awareness in society – be it for example to protect sensitive surfaces – is also increasingly finding its way into the construction industry. Bohlen & Doyen recognised this trend at an early stage, becoming the first provider on the German market to introduce the environmentally friendly and efficient horizontal drilling process for the construction of supply and disposal pipes and cable conduits and thus setting a milestone in civil engineering.
Our services:
- Horizontal drilling up to 2000 m length
- Renovation of existing pipelines
- Installation of horizontal filter wells and drainage systems
Our strength:
The flexibility to be able to carry out complex infrastructure projects both as an overall project – beginning with the drawing up of the drilling planning through to the actual drilling work – and also as contract work for civil engineering and pipe construction works, or just to act as a contractor for the horizontal drilling works, make us an ideal partner for planning and engineering companies, energy suppliers and clients in the field of civil engineering and pipeline construction. As a pioneer of this technology, Bohlen & Doyen is constantly striving to offer improvements and innovations in order to meet the ecological requirements of customers.
