Why Choose GSI as Your Cased Micropiles Contractor

  • Turnkey Design-Build – In-house geotechnical engineers and field crews manage every phase, from concept through installation, providing one accountable partner for design and construction.
  • Rapid Mobilization – Our nationwide footprint and compact, limited-access rigs enable fast start-up in congested corridors and interior spaces.
  • High Load, Small Footprint – Steel casing combined with grout and reinforcement delivers exceptional compression, tension, and shear capacity in restricted work zones.
  • Low Disruption – Drilled-and-grouted installation produces minimal vibration and reduced spoil—safe for historic, occupied, or operational facilities.
  • Safety and Quality Management – Comprehensive procedures, load testing, and documentation meet or exceed industry standards, ensuring consistent performance.

What Are Cased Micropiles?

Cased micropiles are small-diameter, drilled, and grouted deep foundation elements. A high-strength steel casing is advanced during drilling; once at design depth, a central reinforcing bar is installed and the pile is grouted to create a strong, composite element.

The casing prevents ground loss in loose or collapsing soils and can extend to rock or dense strata, providing dependable end-bearing and bonded resistance in challenging geologies.

Micropile-Foundation

Applications & Benefits

  • High Capacity: Composite casing, grout, and reinforcement provide high compressive, tensile, and shear strength.
  • Versatility: Performs effectively in loose soils, fill, and rock; casing mitigates cave-ins during drilling.
  • Restricted Access: Compact equipment and small-diameter elements fit tight urban or interior environments.
  • Minimal Vibration: Protects adjacent or sensitive structures during installation.
  • Reduced Spoil: Smaller bore volumes minimize material handling and disposal for greater efficiency.
  • Depth Range: Can extend to deep bearing horizons for adaptable foundation design.

How GSI Designs & Installs Cased Micropiles

  • Assessment & Testing – Review subsurface data, define load and deflection requirements, and conduct trials or proof tests as needed.
  • Design-Build Engineering – Determine casing dimensions, steel grade, bond length, and reinforcement; detail corrosion protection and connection systems.
  • Drilling and Casing – Advance casing while drilling to design depth, managing spoils to reduce site impact.
  • Reinforcement and Grouting – Install central bar, pressure-grout to form a composite element, and develop bond within soil or rock.
  • Testing and Integration – Perform load testing, install caps or grade beams, and deliver as-built documentation and maintenance guidance.

Client Reviews

Geohazard Repair in Kentucky

GSI, thanks for another successful project. It is always nice to work with you and your field crews. We are currently experiencing flooding here in [this area], so I am sure we will be utilizing your services once again in the near future. The repair was “headache free” and that is very nice, to have a company and crew, come in do their job. You would be surprised how many contractors come in and are not as safety oriented and headache free as yours and for that reason, I am writing this email to let you know as a manager I appreciate the professionalism.

Professional and Cooperative Crew in New Mexico

Marty, I really appreciate all of your cooperation and the cooperation of your crew. They’re great people doing an amazing job. We have placed all of the first 4 rows with very little problems as of Saturday the 28th of March. These guys really deserve a pat on the back from my standpoint. I know they’ve performed a lot of work elsewhere but, this job is going amazing. You have a great crew and they know their jobs very well. The most standoutish part is that they get along on site great and perform in a very professional manner. Thank you for all your help Marty.

On-Schedule and Professional Project Support in Virginia

As told by GSI Project Development Engineer: I was happy to take a call from [the Residency engineer] today and listened to him tell me how happy he was with the performance of Dylan and entire crew at the Garden Creek site. He had great things to say about the competence, work ethic, and professionalism of the whole team out there, and wanted to thank Dylan for the excellent communication as the project has unfolded. This is no small compliment, as this project began in a potentially negative atmosphere since the public thought we were behind schedule before we ever arrived! Nicely done, guys.
