Steep Slope Drilling Across Wyoming

Wyoming's steep slope drilling needs concentrate along Teton Pass and the Bighorn Mountains, where WYDOT manages granite and limestone faces in terrain defined by both extreme grade and a short high-altitude construction season that compresses every project's available working window.

GSI draws on its SPIDER excavator work when scoping projects like this one across the state.

How GSI Delivers Steep Slope Drilling in Wyoming

Track-Mounted and Walking Excavator Drilling

GSI's SPIDER excavators reach Wyoming's Teton Pass granite faces and Bighorn limestone terrain, positioning drilling equipment where WYDOT's conventional fleet cannot go. This is one application of GSI's broader Soil Nail Launcher™ expertise.

Anchored Drill Platforms

Anchored platforms secure to Wyoming's steepest mountain faces lacking a natural bench, common along the state's most dramatic high-altitude highway corridors. GSI's soil nailing experience informs this approach.

Rope Access Drilling

Rope access technicians drill Wyoming's most extreme mountain terrain by hand and pneumatic tools, working within the state's compressed high-altitude construction season. This draws directly on GSI's engineers work.

GSI's transportation infrastructure experience also informs how these Wyoming projects are scoped from the start.

Wyoming Steep Slope Drilling Process

GSI follows a systematic five-step process to deliver steep slope drilling solutions in WYDOT corridors and beyond.

Step 1

Site Assessment

GSI engineers evaluate conditions and severity at your Wyoming site.

Step 2

Root Cause Investigation

In-house geologists investigate the specific conditions driving the issue, referencing Wyoming's Bighorn limestone, Sherman Granite, and Teton gneiss mountain terrain.

Step 3

Engineered Solution Design

Custom design matched to Wyoming's site-specific geology, hydrology, and infrastructure loading.

Step 4

Design/Build Execution

One team executes the engineered solution under a single WYDOT-ready contract.

Warranty

Why Wyoming Trusts GSI for Steep Slope Drilling

Engineered for Wyoming's conditions. GSI's Wyoming steep slope capability is built for both Teton Pass and Bighorn terrain access and the short high-altitude season WYDOT's mountain corridors demand. Supported by general contractors and our case studies.

Design/build delivery. The same engineers who design also build — removing the friction between design and construction phases.

WYDOT specification compliance. Project records and installation methods conform to state DOT standards starting from first design review.

Client Reviews

Landslide Repair for Road in Wyoming

"We got notice today that GSI has completed the remediation work at the [road] Slide.  WYDOT greatly appreciates the responsiveness from GSI regarding the issues that occurred this spring.  Kirk and I were at the site last week right after they finished installing the micropiles and row of soil nails.  Everything looked great, I hope everything worked out coordinating traffic control with our maintenance folks.  Great job!, it is gratifying to work with such a professional, responsive organization."

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.
