Drilling Tiebacks in Wall

Anchored Earth Retention & Wall Rehabilitation

GeoStabilization International is a trusted tieback contractor delivering design-build anchored earth retention for deep excavations, temporary shoring, and permanent wall rehabilitation across North America. Our engineers and field crews design and install pre-loaded steel bar and strand anchors that add lateral capacity, control deformations, and extend the service life of critical infrastructure.

Whether you’re stabilizing a deep cut, strengthening an overstressed retaining wall, or upgrading bridge abutments and wing walls, we provide turnkey anchor solutions; installed safely and efficiently in limited-access and high-consequence environments.

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.

Organized and Dependable Crew Support in Vermont

You and Chris are awesome to work with! … Your crews that have been here are all very well organized, dependable and get their work done! GSI should be very proud of the crews they have working for them. Thanks again Perry for all your help and assistance!

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.
