Micropiles

Benefits

  • Quick & efficient installation
  • High capacity capabilities in limited access areas
  • Works in all soil types
  • Cased or Uncased

Typical Uses

  • Limited Access, low overhead clearance

  • Micropiles can be used to stabilize foundations adjacent to future excavations
  • Have a design build capacity

Helical Pulldown Micropiles

Chance Helical Pulldown Micropiles are used to form a grout column around the shaft of a standard helical anchor/pile. The installation process can employ grout only or grout in combination with either steel or PVC casing.

Benefits of Pulldown Micropiles include: Resistance to buckling in weak surface soils; Stiffer pile (deflects less at a particular load); Additional corrosion protection in aggressive soils.

Rock Anchors

Rock Anchors are structural members used to provide temporary or permanent resistance to a structural element by pre-loading and locking-in tension load. These anchors are installed by drilling into the rock and resistance loads are achieved by the development of friction between rock and grout interface. The structural member (reinforcement) is typically either solid bar or strand anchor that is set into the drilled hole and grout is applied by tremie the method.
