Civil Engineering for Energy Infrastructure – Stronger Foundations for Tougher Needs

Signal Group focuses on robust foundations and technically challenging earthworks in the energy sector. We perform screw piling, soil cutting, and mass replacement to support battery storage facilities (BESS), solar fields, and substations – precisely, documented, and according to schedule. We are also experts in 110 kV–400 kV transmission line foundations and solar farm 2P and tracker solutions.

Foundations Built to Withstand Time, Load, and Regulatory Oversight

In energy projects, earthworks are not just support work – they are part of critical infrastructure where even minor errors can surface years later. Signal Group teams understand the unique requirements of renewable energy and power networks: frost protection, load-bearing capacity, elevation differences, drainage, electromagnetic compatibility, and documentation are all integral to our foundation design.

We carry out the foundations and excavations with machines that are in our own fleet - without intermediaries. This is directly reflected in the timeliness and quality of the work.
