What Are Micropiles?
Micropiles utilize percussion-driven technology that combines hammering, rotation, and simultaneous grout injection. Unlike end-bearing piles, micropiles rely on the interaction between soil and grout to provide both tension and compression capacities. They are particularly advantageous for drilling through challenging soils and boulders to achieve precise depths as required.
Why TerraFirma?
TerraFirma has consistently invested in equipment, personnel, and systems, along with our partners and suppliers, to ensure a top-quality finished product.
Equipment Investment:
We consistently invest in essential equipment including hammers, drifters, grout plants, high-flow/high-pressure compressors, Hi-Flow Caterpillar All-Terrain Skid Steers, and custom-built high-flow excavators.
- Custom-modified High-Flow Cat 305 excavator
- Cat 359D High-Flow All-Terrain skid steer
- 400/200 Doosan air compressor
- Multiple masts for both excavators and skid steers
- TEI top hammer rigs
- ChemGrout colloidal mixer and pumps
Wealth of Experience – Wide Range of Solutions:
At TerraFirma, we prioritize ongoing training for our installers, foremen, and supervisors at the TEI Micropile Training School, ensuring they stay updated with the latest advancements. Rest assured, our expert engineers and field teams provide cutting-edge knowledge and expertise.

Micropile Applications
When Do You Need Micropiles?
Micropiles are invaluable in various commercial foundation applications aimed at enhancing ground improvement, ensuring soil stability, and supporting foundation underpinning. Similar in function to helical piles, another expertise of TerraFirma, micropiles offer versatility, ease of installation in confined spaces, and a range of design loads tailored to different requirements.
Micropiles are particularly applicable in the following scenarios:
- Addressing existing building settlement
- Addressing accidental undermining
- Addressing anticipated undermining
- Replacing caissons
- Mitigating anticipated soft soils
- Installing mezzanines
- Replacing footings and hold downs for metal and lightly-loaded structures
- Supporting additions, vertical expansions, and increased structural loads
- Ground-mounted solar installations
- Addressing construction errors, elevation discrepancies, and unforeseen discoveries
- Modifying shear walls
- Providing structural support in filled locations
How Micropile
Solutions Work
Micropiles operate by penetrating through tough soils and cobbles using simultaneous percussion, rotary action, and grout injection. As the pile progresses, high-pressure grout is injected into the surrounding soil, forming irregularities that enhance bonding between the soil and the grout.
TerraFirma has pioneered innovative approaches in micropile applications, including the integration of brackets to lift structures after pile installation and unique push pile techniques. This method involves pre-drilling with a down-in-the-hole hammer, filling the hole with grout, and then driving push piles through the softened grout until refusal. This process ensures a solid soil interface, confirms end-bearing capacity, and achieves drive to refusal.
