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:
|
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. |
Helical Piles
Helical pile sections can be installed in areas with limited access or low overhead clearance—typically requiring as little as 7 to 10 feet—making them ideal for use inside existing building or confined spaces.
ADVANTAGES:
Less Noise: Helical piles are installed using torque-driven equipment rather than impact hammers, significantly reducing noise during installation.
No Objectionable Vibration: The installation process generates minimal to no vibration, making it safe for use near existing structures without risk of settlement or structural damage.
No Curing Time or Spoils: Helical piles are installed with minimal soil disturbance and produce no spoils. Since they are load-bearing immediately upon installation, there's no need for curing time— allowing for faster project progression.
