Building the Backbone of Modern Infrastructure

Reliable pipeline and plant construction is essential for a secure energy supply and efficient industrial processes. As demand for resilient infrastructure grows, professional execution, technical expertise, and regional strength become increasingly important.
With locations in Osterwald and Gronau, we are strategically positioned in northwestern Germany to build pipeline and plant construction projects efficiently, safely, and at the highest quality standards. Our clients include municipalities, public utilities, municipal enterprises, and private companies, particularly in the energy supply and conveyor technology sectors, providing tailor-made solutions that meet demanding technical requirements. Through experience, precision, and a strong commitment to quality, we build infrastructure that ensures long-term reliability and supports future-oriented development.

Core Services

Our service spectrum covers the entire project lifecycle, from technical engineering and in-house pre-production to the delivery of turnkey infrastructure. Our expertise in high-performance pipeline construction and advanced Electrical, Instrumentation and
Control (EI&C) technology positions us as a trusted partner for urban utility networks, as well as industrial and petrochemical plant projects. We ensure a reliable supply of utilities through precise process control, specialized assembly, and long-term maintenance.

Petrochemical and District Heating Pipeline Construction

We provide end-to-end planning, construction, and documentation services for underground pressure pipelines and associated facilities in the petrochemical sector.

Our Expertise Include:

Maintenance of submersible pump drives and tanks
Fabrication of load-bearing steel structures
Pre-production in our own assembly halls
Delivery and final assembly directly on the construction site

With many years of experience and our own highly qualified specialists, we are proficient in working with steel, cast iron, glass fibre-reinforced plastic (GRP), and polyethylene (PE) piping systems across all pressure classes. Our range of services also includes the maintenance and repair of submersible pump systems and tanks, as well as the fabrication of load-bearing steel structures. We prefabricate assemblies and complete systems in our own workshops, deliver them to site, and carry out installation and commissioning.
