Helical Piles

Helical piles can often prevent further foundation sinking by transferring a majority of a building’s weight into deeper soil. A foundation pile helps direct the weight of a structure into more stable soil, ensuring long-term stability. Foundation repair is a common need.  If you’ve noticed problems in your home or business such as windows or doors that won’t open, cracks in sheet rock or your slab or basement, or uneven or cracked floors, your foundation might be sinking to one side.

Helical piles present many advantages including:

  • Environmentally Friendly
  • Vibration Free
  • All Weather
  • Re-usbale
  • Removable
  • Fast Installation
  • Low Noise
  • Cost Effective

Helical soil nailing is the process of using helical shafts to reinforce slopes and blocks of soil for earth retention and stabilization. Helical soil nails have helical bearing plates spaced along the entire length of the shaft for continuous bonding with the soil. As opposed to grouted anchors which are generally 4 to 6 inches in diameter, helical soil nails mobilize a bonded diameter that is 8 or 10 inches in diameter for a greater reinforcing effect. Soil nailing permits the use of relatively thin shotcrete facing or steel mesh to prevent raveling between nails as opposed to the heavy reinforced facing required for soil anchor walls. Since helical soil nails are intended for earth reinforcement, the termination criteria for the anchors is based on length as opposed to minimum installation torque. Soil nail lengths then are fixed length (typically 0.7 to 0.8 times the slope/wall height). Fixed length allows for the shafts to be manufactured with an integrated thread bar adapter. There is no need to cut-off and re-drill the shaft. Helical soil nails have many advantages over traditional grouted soil nails. Installation is very rapid. There are no issues with caving soils and/or ground water, and there is no waiting for grout to set.
