Slope stabilization is geology-driven work. When the drill encounters a different soil profile than the design assumed, your sub either has an engineer on site with authority to adapt the nail pattern and drainage layout — or you get a three-week design cycle and a change order. Most specialty subs produce the latter.
GeoStabilization International fields geotechnical engineers alongside installation crews on complex slope scopes. Our Soil Nail Launcher™ installs nails exceeding 1,800 LF per day on accessible terrain, and our spider excavators work grades that exclude conventional equipment.
As a slope stabilization subcontractor, GeoStabilization International provides engineered, self-perform installation across every major slope stabilization technique.
Our soil nail wall crews install nail-and-shotcrete systems on highway cut slopes, commercial pad excavations, and hillside infrastructure projects. The Soil Nail Launcher™ compresses drill-and-grout cycles on large-scale scopes.
Where slope geometry requires deeper reinforcement, tieback-anchored wall systems transfer load to competent strata. GSI engineers design the anchor pattern and our crews drill, grout, and test every tieback on site.
Horizontal drains relieve pore pressure that drives rotational slope failure. GeoStabilization International integrates drain installation into slope repair scopes — eliminating the coordination burden of hiring a separate drainage sub.
Structural and aesthetic shotcrete facing provides permanent surface protection for soil nail and tieback walls. Our crews handle both structural gray and owner-specified sculpted finishes.
Standard slope stabilization drill rigs work on grades up to 30–35 degrees. Beyond that, most specialty subs either decline the scope or add a second sub for access — adding cost and schedule to your project. GeoStabilization International owns spider excavators that operate on grades up to 80 degrees and purpose-built limited-access drill rigs that reach terrain no standard equipment can touch.
That equipment advantage translates into fixed-price confidence on difficult terrain. We don't build uncertainty into our bid when we've already deployed similar equipment on hundreds of comparable slopes — giving your proposal a number you can rely on.
