What Are Micropiles?

Micropiles are a percussion-driven product that hammers, rotates, and injects grout simultaneously. Micropiles are not end-bearing, instead relying on the soil/grout interface to provide both tension and compression capacities. They have the advantage of easily drilling through hard soils and boulders to a specific required depth.

Why TerraFirma?

TerraFirma has consistently invested in equipment, personnel, and systems, along with our partners and suppliers, to ensure a top-quality finished product.

Micropile Applications

When Do You Need Micropiles?

Micropiles are useful in a variety of commercial foundation applications for the purpose of providing ground improvement, soil stability, and foundation underpinning. Micropiles are quite similar in form and function to helical piles, another of TerraFirma' expert foundation support and repair tools. Micropiles are smaller, easy to install in a variety of tight-access environments, and offer a wide variety of design loads to fit the needs of different scenarios.

Micropiles can be applied in any of the instances below:

  • Addressing existing building settlement
  • Accidental undermining
  • Anticipated undermining
  • Caisson replacements
  • Mitigation of anticipated soft soils
  • Mezzanine installations
  • Footing replacements and hold downs for metal and lightly-loaded structures
  • Support for additions, vertical expansions, and generally increased structural loads
  • Ground-mounted solar
  • Managing construction mistakes, elevation busts, discovery of unknowns
  • Modifications to shear walls
  • Structural support in fill locations

 

How Micropile Solutions Work

Micropiles work by advancing through hard soils and cobbles, via simultaneous percussion, rotary, and grout injection. As the pile advances, the grout is injected at high pressure into the soil surrounding the shaft, creating irregularities in the soil as it advances that increase the bond between the soil and the grout.

Micropile application


TerraFirma has pioneered several unique solutions in micropile applications, including the combined use of brackets to lift structures post-installation of the pile and unique push pile applications. This process entails pre-drilling with a down-in-the-hole hammer, filling the hole with grout, then advancing push piles through the soft grout and driving to refusal. This provides a soil interface combined with a drive to refusal and an end-bearing capacity verification.
