Drilling Technology

In special foundation engineering, we distinguish between the following application methods:

  • Horizontal drilling method
  • Soil auger
  • Dynamic pipe jacking
  • steel pipe drilling

Horizontal directional drilling

This fast and environmentally friendly process does not cause damage to surfaces or inconvenience to road users or residents.

Application examples:

  • Crossing federal, state or municipal roads
  • Underpassing streams or rivers
  • Crossing railway tracks
  • Longitudinal drilling in asphalt surfaces

Basic information:

  • Drilling length up to 250 m
  • Pipe materials: PE (protective pipes), single and multiple feed
  • Pipe diameter OD 50 mm – OD 300 mm
  • Soil classes 1-7
  • controlled displacement-free process

Soil auger

This fast and environmentally friendly process does not cause damage to surfaces or inconvenience to road users or residents.

Application examples:

  • Crossing municipal roads
  • Crossing asphalt surfaces
  • Construction of house connections

Basic information:

  • Drilling length up to 25 m
  • Pipe materials: PE (protective pipes)
  • Pipe diameter OD 32 mm – OD 160 mm

Dynamic pipe jacking

This environmentally friendly process does not cause damage to surfaces or cause disruption to road users or residents.

Application examples:

  • Crossing streets
  • Crossing rivers
  • Crossing railway tracks
  • Crossing closed surfaces

Basic information:

  • Drilling length up to 80 m
  • Pipe materials: steel pipe
  • Pipe diameter OD 150 mm – OD 800 mm
  • Soil classes 1-6
  • Non-displacement process

steel pipe drilling

This fast and environmentally friendly process does not cause damage to surfaces or inconvenience to road users or residents.

Application examples:

  • Crossing streets
  • Crossing railway tracks
  • Crossing closed surfaces

Basic information:

  • Length: 30 m
  • Materials: steel pipes
  • Diameter DA 152 mm – DA 412 mm
  • Soil classes: 1-5
  • Soil classes: 6-7 (for down-the-hole hammer)
