The Advantages of STELCOR® Drilled-In Displacement Micropiles

When load demand meets poor soil, STELCOR® piles by IDEAL GROUP offer an elegant solution that bridges the gap between traditional deep foundations and ground improvement systems.

Unlike driven or auger-cast piles, STELCOR® Drilled-In Displacement Micropiles (DDMs) create strength through controlled soil displacement—not removal. The steel core and grout bond form a high-capacity element installed with minimal vibration and spoil, making it ideal for sensitive sites, restricted access, or contaminated soils.

At Garbin GeoStructural Group, we’ve designed, peer-reviewed, and implemented STELCOR® systems for both new construction and retrofit applications. What sets STELCOR® apart isn’t just its clever geometry- it’s the control. Installation torque is monitored throughout the process to provide valuable insight into subsurface conditions and consistency- but unlike some other systems, installation torque does not directly correlate to capacity. The true performance of STELCOR® piles is verified through sound engineering analysis, proper design methodology, and, when needed, load testing.

In practice, this system offers faster installations, cleaner sites, and dependable results. When engineered correctly, STELCOR® piles can achieve the same or greater load capacities as much larger deep foundation systems- often at a fraction of the time and cost.

For complex soil profiles or tight jobsite logistics, STELCOR® represents what we value most: innovation with integrity- solutions grounded in science, not guesswork.
