Services

Three methods, one goal.

For every route we choose the method that suits the ground, the length and the diameter. If you are unsure, send us the route and we will recommend a technology.

ZOLMAT drilling rig and supply truck at a substation

Horizontal directional drilling

An arc beneath the surface: under a road, railway or river, with just one entry and one exit point.

  • up to Ø 1,000 mm
  • up to 15 m deep
  • 4.5–80 t pullback

Typical jobs: motorways and rail embankments, under rivers and watercourses, city centres, congested utility corridors.

Details

Soil displacement hammer

The fastest way to the house: a small pit and several connections a day.

  • Ø 55–200 mm
  • up to 25 m
  • 480 blows / min

Typical jobs: house connections, under pavements and driveways, crossing property lines.

Details

Steel pipe jacking

Load-bearing steel casing under tracks and main roads, without settlement.

  • up to Ø 1,100 mm
  • 240 t thrust
  • no settlement

Typical jobs: under railway tracks, under main roads, with traffic still running.

Details

Fleet and contract drilling

Rig, driller, drilling fluid and transport from one source, on the agreed day.

  • 14 rigs
  • ~300 t combined
  • own trucks

Typical jobs: subcontract work, rig with driller, fluids, tracking, welding.

Pipe welding

We weld PE pipes right on site.

We join PE, PP and PVDF pipes by heated-tool butt welding from Ø 90 to 355 mm, with our own ROTHENBERGER ROWELD P355 B and to DVS guidelines.

Butt welding PE pipes on site

What we install

From the main line to the house connection.

PE water and pressure mains, gas distribution lines and service connections, sewage pressure mains, medium and low voltage cables in ducts, fibre and microduct networks, and steel and PE casings for utility crossings.

In sand, silt, clay and gravel, and with dual-rod rigs even in rock. We butt-weld PE pipes on site with our own welding machine.
