Illini Drilled Foundations, Inc. has a full fleet of drilling equipment available, including Conventional Drilling Equipment and Limited Access Drilling Equipment, as well as additional equipment to handle countless situations and scenarios. No matter the machine, our commitment to quality and safety remain constant. We are constantly researching equipment productivity as well as innovations in drilling machinery.
Low Clearance Rigs
CAT 312 LoDrill
The Cat 312 LoDril is ideally suited for digging in confined areas, where overhead clearance is limited.
FEATURES: Mounted on an excavator, giving it all of the advantages of being track-mounted, and adds the capability of a highly productive drill rig. Easily drills in confined areas with limited overhead clearance.
Kelly Performance: 16,000 ft/lbs of torque // 30,000 lbs of crowd
Shaft Diameter: Up to 48" in diameter
Digging Depth: Up to 35 ft deep
CAT 330 LoDrill
The Cat330 LoDril has many of the features as the Cat312 LoDril, but is capable of handling bigger jobs. It features a larger shaft diameter and more torque than its counterpart.
FEATURES: Heavy duty foundation drill mounted on an excavator. Easily drills in confined areas with limited overhead clearance
Kelly Performance: 50,000 ft/lbs of torque // 15,000 lbs of crowd
Shaft Diameter: Up to 96" in diameter
Digging Depth: Up to 45 ft deep
Watson Excadrill EDT-7
The Watson EDT-7 is a track mounted machine ideally suited for working under existing power lines due to its mast height of approximately 20 feet. It also has maximum reach capabilities of 17 feet from track to center of shaft.
FEATURES: Short boom height and farther reach capabilities make this machine ideally suited for many projects.
Kelly Performance: 60,000 ft/lbs of torque // 18,500 lbs of crowd
Shaft Diameter: 18" to 10'
Digging Depth: Up to 45 ft deep
The Soilmec 312 is a European-style, track-mounted rig, a smaller counterpart to the SR 65.
FEATURES: Track-mounted for easy access to hard-to-reach job sites, with swift set-up that easily converts for auger cast pile.
Kelly Performance: 92,000 ft/lbs of torque // 27,875 lbs of crowd
Shaft Diameter: 18" to 12' in diameter
Digging Depth: Up to 100 ft deep (2006)
The Watson 1100 is a truck mounted machine suited for smaller projects with easy access such as drilling on existing pavement or beside roadways.
FEATURES: Mounted on a truck for easy access and maneuverability.
Kelly Performance: 40,000 ft/lbs of torque // 20,000 lbs of crowd
Shaft Diameter: 81" to 4' in diameter
Digging Depth: Up to 60 ft deep
Our fleet includes 2 Watson 3110's. These reliable machines are flexible enough to handle hard-to-reach sites, but tough enough for rock drilling and coring.
FEATURES: Heavy duty rig handles difficult drilling situations, with a configuration for larger diameter shafts and rock drilling. Track mounted for easy access at hard-to-reach job sites. Light-weight configuration allows for easy mobility.
Kelly Performance: 113,000 ft/lbs of torque // 50,000 lbs of crowd
Shaft Diameter: 18" to 10' in diameter
Digging Depth: Up to 80 ft deep
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:

- 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 SR-65 and SR-312 to CFA
- Stillwell Grout Pump - 110 cubic yards per hour
- 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.
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.
