Landslide Repair Across Colorado's Mountain Corridors

Active landslide complexes along Colorado's I-70 mountain corridor, US-40 at Berthoud Pass, CO-82 near Aspen, and Gunnison National Forest roads demand engineering solutions that address the root cause of instability—not just the surface symptoms. GeoStabilization International deploys Soil Nail Launcher™ technology, slope pinning systems, and engineered retaining structures to permanently stabilize Colorado's most problematic slides.

Our Soil Nail Launcher™ fires proprietary SuperNails™ into failing slopes at 250 mph without excavation—a capability no competitor can replicate. This means your landslide repair starts faster, costs less, and works in ground conditions where conventional drilled soil nails physically cannot be installed. One team from bore log to final nail, backed by a performance warranty.

Colorado's Active Landslide Zones

Colorado's mountain terrain produces chronic landslide conditions driven by glacial till deposits, weathered Mancos Shale formations, steep colluvial slopes, and intense spring snowmelt cycles. The I-70 mountain corridor, US-40 at Berthoud Pass, CO-82 approaching Aspen, and roads through the Gunnison National Forest experience recurring slope failures that close highways, damage infrastructure, and threaten public safety.

Soil Nail Launcher™ Technology in Colorado

GeoStabilization International's patented Soil Nail Launcher™ fires proprietary SuperNails™ into failing slopes at approximately 250 mph using compressed air—no excavation, no drilled boreholes, no casing required. This technology installs reinforcement in actively moving slides and collapsing ground conditions where conventional drilled soil nails physically cannot be placed. Colorado's clay-rich, moisture-sensitive landslide deposits are precisely the conditions where our Launcher technology outperforms every alternative.

Design/Build Landslide Repair for CDOT

CDOT and Colorado's transportation community benefit from GSI's integrated design/build model. One team—our in-house geotechnical engineers and field construction crews—designs the solution, installs the reinforcement, and stands behind the performance warranty. No coordination gaps between a design consultant and a separate contractor. No finger-pointing when conditions differ from design assumptions. One contract, one point of accountability, and a solution timeline compressed by 40% or more compared to traditional procurement.

Landslide Repair Process for Colorado

GeoStabilization International's integrated design/build approach compresses Colorado landslide repair timelines from months to weeks.

Step 1

Emergency Response

Call (855) 599-5217 for immediate landslide response. Colorado-based crews mobilize within hours for active slope failures.

Step 2

Failure Analysis

In-house geotechnical engineers investigate failure mechanisms, subsurface conditions, and groundwater influences at your site.

Step 3

Integrated Design

Custom soil nailing, slope pinning, or retaining system design—produced by the same team that will build it.

Step 4

Launcher Deployment

Soil Nail Launcher™ fleet installs SuperNails™ at 250 mph into actively moving slides—no excavation, no waiting.

Warranty

Design/build/warranty coverage means GSI stands behind the long-term performance of every installed reinforcement element.

Performance Warranty on Every Colorado Project

GeoStabilization International does not just build landslide repairs—we warranty them. Our design/build/warranty delivery model means we stand behind the engineering analysis, the construction quality, and the long-term performance of every soil nail, every anchor, and every retaining structure we install across Colorado. This warranty commitment is why CDOT and Colorado's transportation community choose GSI for their most critical slope failures.

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.
