Everything below the surface.

Civil works from a single source: from breaking out the surface through excavation, pipes and cables, house connections and directional drilling to the finished road. For network operators, municipal utilities, municipalities, construction companies and businesses. See where we have already built on the project map.

All from a single source

One contract.
One point of contact.

We take on the entire chain, from breaking out the surface to disposal. You don't have to coordinate several firms, and there are no gaps between trades on site. Our civil works guide explains how it all works in detail.

Civil works · Pipe & cable laying

Pipes and cables for everything that keeps a city running.

We dig trenches, build routes and lay pipes and cables for power, water, gas and telecommunications. Coordinated with network operators and the local authority, cleanly backfilled and handed over on schedule.

  • Route construction for utility companies and network operators
  • Laying pipes, cable protection ducts and empty ducts
  • House connections for power, gas and water
  • Crossings, open-cut or trenchless
  • Construction pits and bulk excavation
  • Measurement and documentation

House connections

From the footpath to the basement.

For fibre, power, gas and water, we handle the civil works for the house connection: a trench or impact mole across the property, a building entry through the basement wall, and a surface that looks just as it did before.

  • Trench across the property or impact mole
  • Core drilling and building entry, sealed against water and gas
  • Fibre house connection up to the APL
  • Civil works for power, gas and water connections
  • Reinstating front gardens, driveways and paving
  • Coordination with the network operator and property owner

We open surfaces in a controlled way and reinstate them properly once the works are complete. Clean edges and transitions included.

  • Controlled opening of asphalt and paving
  • Professional base course installation
  • Asphalt surfacing and paving
  • Building footpaths and paths
  • Clean edges and transitions
  • No settlement, thanks to proper compaction

  • Route construction, open-cut or trenchless
  • Laying duct bundles to plan
  • Blowing in the fibre
  • Installing street cabinets (NVT)

Backbone · Horizontal directional drilling (HDD)

Large drilling rigs for long runs underground.

For backbone routes, the major fibre links between towns and network nodes, we drill beneath the surface with HDD rigs. Roads, railway lines, watercourses and fields remain untouched, and traffic keeps flowing.
