Additional Equipment


In addition to our drilled shaft machinery, Illini Drilled Foundations hosts a variety of equipment which allows for work to be performed in countless situations and scenarios. This equipment includes:

  • Soilmec 321 ACP Conversion
  • APE Auger Cast Equipment
  • Model 50 Drive Head and Model 240 Power Pack
  • Ice 55 Drive Head and Power Pack
  • Auger Cast Equipment to Convert Soilmec 312 to CFA
  • Olen Grout Pump - 110 cubic yards per hour
Auger Cast Piles
Auger sections can be manufactured to accommodate installation of auger cast piles inside existing building with a minimum clearance of 7 to 10 feet.
ADVANTAGES: 
Less Noise: Drilled and pumped (not driven), eliminating the hammer-impact noise
No objectionable vibration: With no driven hammer, this allows the auger cast to install adjacent to existing structures, without damage to nearby structures or settlement.
No casing required: During installation, the earth-filled auger maintains the shape of the pile hole during the drilling phase. The pressures produced by the grout pump during the withdrawal and grouting phase exceed the lateral pressures exerted by the soil, and while the grout is still fluid, the lateral pressures per foot of depth of the grout exceed those pressures per foot of depth of the soil.
