and limited access applications
The technique of using pin piles has been around for several decades and is typically used for projects that require lighter loads or for foundation repairs. The piles are also highly-practical and the most inexpensive foundations piles. Pin piles are pipe piles with a small diameter is 3 or 4 inches and driven to refusal.
Pin piles originated in the United States but have spread to other parts of the world due to their practicality and high-capacity. They’re ideal for building foundations on construction sites with sensitive surroundings, poor ground conditions, difficult access, or restricted vertical clearance. Pin piles are well-suited for projects that call for arresting ground movements, foundation underpinning, and increasing the capacity of existing foundations.
Pin piles can be constructed to considerable lengths with a Galvanized Sch. 40 or 80 pipes and driven to refusal with a hydraulic rammer that’s usually mounted on a skid steer or a mini excavator.
