Foundation construction

Large-diameter rotary drilling rigs

With our large rotary drilling rigs BG20H and BG24H, we are able to place 150 cm thick piles into the ground. Depending on the building project and subsoil, we use the more accurate method of cased drill-foundation piles or the more cost-effective non-cased piles.

Furthermore, we execute CFA-boreholes with long hollow stem augers and use special drilling systems such as soil mixing wall systems, FOW piles and displacement piles.

Drill-foundation pile walls are used as waterproof sheeting to secure pits at great depths, as deep foundations for constructions in flood control areas, for creating launch and target pits in underground pipe drives and also for slope and flotation control.

Anchor drilling rig

Thanks to the 360° blade angle this machine enables the following to be realised:

  • Gewi anchors
  • Ischebeck anchors
  • Blast hole drilling

All in the most extreme conditions.

SONNTAG offers a wide range of foundation construction methods covered by its own professionals and machinery. We have worked in sheeting technology using different equipment and technologies for years (see our range of services in sheeting technology).
