Landslide Repair Challenges Across Montana

Montana's Clark Fork River Valley, Flathead Valley, Beartooth Highway (US-212) present landslide repair conditions that demand engineered solutions. The region's unique geology, climate patterns, and infrastructure density create hazard scenarios requiring specialized expertise that general contractors cannot provide. GeoStabilization International has engineered solutions across these corridors using soil nailing, slope pinning, and proprietary technology developed through 8,000+ completed geohazard projects.

How GeoStabilization International Addresses Montana Landslides

Our engineering team analyzes each site's specific conditions—geology, hydrology, loading demands, and failure mechanisms—to design a solution precisely matched to the hazard. For Montana's Clark Fork River Valley corridor, our approach combines in-house geotechnical engineering with field construction under one design/build contract. This integrated delivery eliminates the coordination gaps, change orders, and schedule overruns that traditional design-bid-build procurement creates.

Emergency Response Capability

When a geohazard event strikes Montana's infrastructure, GeoStabilization International maintains 24/7 emergency mobilization with pre-staged equipment and regional crews. Our team deploys within hours—not the weeks that traditional contractors require. One call activates an integrated response: engineering assessment, solution design, and construction execution under one contract. Every Montana project is backed by FHWA-compliant engineering designs produced by our in-house geotechnical engineers and professional geologists.

Why Montana Chooses GSI

Montana's infrastructure operators face a choice: hire a general contractor who subcontracts the engineering and rents the equipment, or hire the only geohazard firm that owns the technology, employs the engineers, and warranties the performance. GeoStabilization International has completed more geohazard projects than any firm in North America—8,000+ and counting. Our patented Soil Nail Launcher™ fleet, 700+ dedicated specialists, and in-house engineering team deliver landslide repair solutions that compress timelines, reduce costs, and come backed by a design/build/warranty commitment no competitor can match.

Client Reviews

Landslide Repair for Homeowner in Colorado

I would like this to be a letter of appreciation and gratitude on a job well done. Our house was first threatened by a landslide back in June, 2017 and it has been a journey that has been both stressful and scary. And yet, every cloud has a silver lining and in this case the support, encouragement and character of everyone we met from GSI has indeed been a gift throughout this journey.

GSI was recommended by Steve Pawlak and we met Nathan Thompson early on. Nathan is a person who inspires trust and our first impression was verified throughout the process that led to a retaining system that has saved our house. As with everyone, and I mean everyone we met, we felt we had a group of people who were on our side.

There were challenges that were overcome; the patience needed along with several visits to get the project underway, a renegotiated plan and bid when the insurance settlement squeezed the payment amount, and a time crunch that led to a change in plans where the panels were poured on the hillside, that allowed for the project to be started as quickly as possible.

The crew that showed up to do the work was respectful, always ready to explain what was happening and was also timely, hard working and ready to go the extra mile. A great group of people with positive attitudes who seemed to genuinely work well together.

Watching Spike work on that excavator was awe inspiring. One of my favorite moments was filming him on my phone to show my office secretaries at the Elementary School. I recorded a "holy shit" without knowing it when he pulled off an amazing stunt coming off a ledge and then being horrified when that came out while I was sharing the video at school. I was able to laugh later.

Thank you again and if I can ever serve as a reference, please let me know.

Emergency Landslide Repair in Wyoming

In 2017, another well above normal snowpack winter and heavy spring rains resulted in 23 new landslides, which damaged or threatened WYDOT roads. WYDOT turned to GSI to help respond to these emergency situations. GSI was able to respond very quickly and in most cases had personnel on site to assess the site within 24 hours. They would provide a proposal for remediation with a preliminary design and estimated costs within 48 hours in most cases. During 2017, GSI was selected to perform remediation with contracts at six separate sites. In all cases, they were prepared to mobilize to the sites and begin work within a week of being given notice to proceed.

A unique element of these emergency contracts was a partnership, between WYDOT and GSI, by which WYDOT provided some logistical support such as traffic control and providing water for drilling operations so that GSI could focus its efforts on performing the specialty work. This arrangement resulted in cost effective, efficient, successful projects. When responding to emergency landslide repair, time truly is money, the sooner a landslide can be remediated before it has a chance to grow, the less expensive it is to repair. In the past, WYDOT has experienced situations in which, landslides could possibly have been remediated quicker, experienced further failure during drawn out conventional design and contracting methods resulting in higher costs due to the additional failure. GSI uses various types of innovative geo-technology in their landslide remediation projects….

All of these projects were completed on schedule, even with cold weather conditions and snow storms ….

All of the stabilization projects that GSI completed for WYDOT included a warranty to repair any of the remediation that would happen to fail, but to date none of the work that they have performed has required any repair. I would highly recommend GeoStabilization International to perform emergency landslide and slope remediation work. They have the resources, personnel, and expertise to respond to your emergency in a timely, professional manner.
