Roterra Piling - Pre-Drilling


Why Pre-drill?

Pre-drilling is used normally in two cases:

  1. To drill through frost in winter season

  2. Help the pile penetrate dense soil to the design depth


Depending on the type of site terrain and the size of holes to be pre-drilled, a truck mounted mobile rig or a crawler type hydraulic rig can be used. Roterra offers a diverse fleet of predrilling equipment.


Advantages of Pre-drilling

  • Increases pile productivity

  • Reduces pile non-conformances related to plumb issues

  • Reduces damage of pile tip or helix leading edge
