Equipment
At a glance: Unlimited Drilling & Foundations publishes an equipment list aimed at tight and steep sites, including mini drill rigs and a mini crane that it says need only 36 inches of access width.[1] The list is the company’s, not an independent inspection.
The published equipment list
The official resources page lists the following, in the company’s wording: a tripod drilling rig for small-diameter holes and soil investigation; a mini drilling rig for holes up to 18 inches in diameter; a mini caisson drilling rig for holes up to 36 inches in diameter that requires only 36 inches of width for access; a mini excavator; a mini Bobcat; a mini crawler crane that also requires 36 inches of width, used to set steel cages or beams and to move materials on steep hillsides; a dump trailer for soils and debris; a Bobcat for moving material; a job box; helical-pier and tie-back installation equipment; push-pier installation equipment; and a stock of smaller tools such as jackhammers, saws, roto-hammers, drills and laser levels.[1]
How to read the list
This is the company’s inventory description, not an inspected inventory dated by a third party. It is still useful, because it shows the firm is pitching limited-access hillside work rather than only open-site production.[1] Helical piers, tie-backs and push piers, if used, are designed elements; naming the installation equipment is not the same as saying every job will use them.
Access claims
The repeated 36-inch access width for the mini caisson rig and the mini crane is the most specific claim on the page.[1] Anyone with a tight side yard should measure the actual clear width, including gates, meters, and overhead obstructions, and should ask the company to confirm that the published figure still applies to the machines it will send.
How the list maps to methods
Read as a method map rather than a catalog, the official list groups into investigation and small-diameter drilling (tripod and mini rigs), limited-access caisson work (the 36-inch-access caisson rig and mini crane), earth moving and spoils (mini excavator, Bobcat, dump trailer), and alternative foundation elements (helical-pier, tie-back and push-pier installation equipment), plus hand tools.[1]
Helical piers, tie-backs and push piers are designed systems. Naming installation equipment means the company presents itself as able to install them; it does not mean every foundation repair will use them, and it does not replace an engineer’s choice of element.[1] Soil investigation with a small-diameter or tripod rig, if offered, is also not the same thing as a signed geotechnical report unless a licensed professional produces that report.
Because this wiki does not reuse company photographs, readers who want to see the machines should use the official resources page. Any bid that depends on a 36-inch access path should still be checked against the actual gate, side-yard and overhead clearances on the lot.[1]
Equipment wears out and is replaced. The list transcribed here is the list as published when this site was compiled on 9 November 2026, not a permanent fleet certificate.
Questions readers ask
Is this a complete fleet list?
It is the list on the official resources page as of the research for this wiki. It may change.
Does listing a pier machine mean the company will recommend piers?
Not automatically. Method choice should follow the engineer and the soils report.
Are photos of the equipment on this wiki?
No. This reference does not use the company’s project or equipment photographs.
