Micropiles Techniques

A Micropile is a small diameter, typically less than 300mm, drilled and grouted non-displacement pile which is heavily reinforced and carries most of its loading on the high capacity steel reinforcement.

Applications

For Structural support (Case 1)
  • New Foundations
  • Under pinning of existing structures
  • Seismic retrofitting of existing structures
  • Scour protection
  • Earth retention
  • Tension anchors
In situ Reinforcement (Case 2)
  • Slope Stabilization
  • Earth retention
  • Ground strengthening and protection
  • Settlement reduction

Advantages

  • Used where need of minimal vibration or noise is of prime importance
  • Easy laying at low head room
  • Easy installation at any angle below the horizontal
  • Offer a practical and cost-effective solution to costly alternative pile systems as well as a solution to job sites with difficult access
  • Do not require large access road or drilling platforms

Disadvantages

  • Minimum lateral capacity to vertical micropiles
  • High slenderness ratio
  • Requires specialized and experienced applicators
  • Initial higher costing
