Micropile Foundation Systems: Expertise and Applications

Durable and Dependable Solutions for Challenging Soil Conditions

At Tri-State Drilling, we are a leading micropile foundation installer. Micropile, also known as mini piles, pin piles, needle piles, and root piles, are known for their small-diameter, high-capacity solutions.  This system ensures your structure stands on a solid and reliable foundation. Using advanced techniques and equipment, we deliver customized micropile solutions to meet your specific needs.

Versatile Applications

Structural Support

Provides robust support for buildings, bridges, and other structures.

Foundation Underpinning

Strengthens and stabilizes existing foundations.

Mass Stability Enhancement

Improves overall stability of slopes and embankments.

Load Transfer

Effectively transfers loads to deeper, more stable strata.

Micropile Installation

Micropile installation involves a small-diameter, non-displacement pile that is drilled & grouted with a reinforced bar.  The pile diameter ranges from 3 to 10-inches, sometimes larger depending on the project.  These systems may require steel casing, and are advanced to the design depth using specialized drilling techniques. Reinforcing steel, usually an all-thread bar or hollow bar, is then inserted into the socket, followed by high-strength cement grout. This grout is pumped into the casing to create a solid, high-capacity foundation element.

“Micropiles offer unparalleled versatility and strength, making them ideal for complex projects.  Our innovative techniques and state-of-the-art equipment allows us to support structures in difficult soil conditions and tight spaces, providing reliable foundations where others cannot.” – Cody Cox, Vice President of Specialty

At Tri-State Drilling, we build our micropiles to the highest standards. Each finished micropile undergoes rigorous load testing to verify its capacity, including tests for compressive (ASTM D 1143), uplift/tension (ASTM D 3689), and lateral (ASTM D 3966) loads. Our meticulous quality assurance process guarantees that our piles meet and exceed industry standards, providing dependable support for your project.

Key Benefits

Load Resistance

Handles compressive, uplift/tension, and lateral loads effectively.

Versatile Equipment

Comprehensive fleet of rigs and tooling for challenging subsurface conditions and restricted access areas.

Minimal Disruption

Allows installation in confined spaces with minimal utility re-routing.

Enhanced Stability

Can be combined with other techniques for unique or complex project requirements.

Quality Assurance

Load testing ensures the highest standards of performance and reliability.
