A Micro Pile is a small-diameter deep foundation element used to transfer structural loads to deeper, stronger soil or rock layers. Typically ranging from 100mm to 300mm in diameter, micro piles are reinforced with steel bars or hollow steel sections and filled with high-strength grout.
They are ideal for projects where traditional piling methods are not feasible.
Why Use Micro Piles?
Micro piles are commonly used when:
- Soil conditions are weak
- Access space is limited
- Existing structures need strengthening
- Vibration must be minimized
Because of their flexibility, they are widely used in both residential and commercial projects.
Advantages of Micro Piles
- Suitable for restricted spaces
- Minimal vibration during installation
- High load-bearing capacity
- Works well in poor soil conditions
- Ideal for foundation repair and underpinning
Micro Pile Installation Process
- Drilling a small borehole
- Placing steel reinforcement
- Injecting high-strength grout
- Allowing curing for strength development
This ensures strong bonding between soil and pile.
Applications of Micro Piles
- Building foundations
- Bridge construction
- Retrofitting old structures
- Basement strengthening
- Industrial projects
Conclusion
Micro piles are a reliable and cost-effective foundation solution for challenging construction conditions. Their strength and adaptability make them a preferred choice for modern engineering projects.
