Network construction
We ensure safe and stable networks of tomorrow
Our modern world consists of numerous different supply networks. People need a high level of mobility and availability – that is not only applicable to the world of digitalisation and telephony. A supply of energy, water, heating and telecommunications networks without breakdowns is usually regarded as a matter of course – but it is based on a complex system.
As your partner for future-proof network construction projects, LEONHARD WEISS solves these challenges for all supply networks with outstanding expertise in planning and execution. Thanks to the integration of underground engineering, pipeline construction, and cable installation, we can carry out all services in network construction from one source. Network solutions made to measure are our passion and your key to success.
We support our customers from the beginning. Already during tendering, we can offer you complete consulting and route planning, as well as feasibility studies and the corresponding estimates of costs.
We carry out projects responsibly and fairly. From planning up until repair works, everything is supplied from one source. Thanks to state-of-the-art technology and a committed team we prove that climate-friendly construction is not a matter of tomorrow, but that it starts today. The best example for our experience in the field of sustainable network construction? Our all-electric construction site in Rangendingen in Baden-Württemberg in 2024.
