Soil Nail Walls

Biogen Soil Nail Walls

Soil nail walls are constructed by drilling soil nails on a close pattern and applying 4 to 6 inches of shotcrete facing in lifts.  Soil nail walls provide an economical means to retain soils in a “top-down” construction method.

  • Temporary excavation shoring
  • Permanent site retaining walls
  • Slope stabilization
  • Excavate 5 feet
  • Drill 4 to 6 inch diameter holes and grout in-place an all thread bar
  • Place reinforcement and shotcrete face
  • Proof test 5% soil nails
  • Repeat process to bottom of excavation

When we need a soil nail wall sub again, I highly recommend Subsurface.  They worked with our ever changing schedule without complaining.
