On projects with geotechnical or geohazard scopes, the specialty subcontractor's performance determines more of the project outcome than any other subcontract. A specialty sub who falls behind schedule pulls your structural and paving work with it. One who produces rejected submittals delays owner engineer reviews. One who can't adapt to field conditions creates change orders your project manager absorbs.
GeoStabilization International is built to avoid all three failure modes. Our in-house engineers manage submittals from first draft to owner acceptance. Our Soil Nail Launcher™, spider excavators, and limited-access drill rigs maintain production rates others cannot match. And our field engineers carry design authority on site — when conditions change, we adapt and keep producing.
GeoStabilization International provides specialty geotechnical subcontract services across the full range of geohazard mitigation and geotechnical construction disciplines — a single specialty sub who covers the scope types most prime contractors encounter across their project portfolio.
Soil nail walls, tieback systems, permanent and temporary shoring, and slope drainage are installed by GSI engineers and crews on commercial, transportation, and infrastructure projects. Our Soil Nail Launcher™ provides industry-leading production rates on accessible nail wall scopes.
Catch fences, draped and pinned mesh, rock bolt systems, and scaling are executed by our specialty rockfall crews with proprietary access equipment, including spider excavators and limited-access rigs reaching terrain that prohibits conventional equipment.
Compaction grouting, micropiles, permeation grouting, and underpinning address bearing capacity, settlement, and foundation deficiency scopes. GeoStabilization International's confined-space rigs handle interior and restricted-access installation environments.
When a geohazard event threatens your project timeline, our emergency response teams mobilize within 24 hours — stabilizing the failure, restoring access, and beginning permanent repair under the same subcontract framework as your scheduled work.
GeoStabilization International's proprietary equipment — the Soil Nail Launcher™, RailJET™ grouting system, and spider excavator fleet — provides measurable performance advantages over specialty subs who rent standard equipment. The Soil Nail Launcher™ installs soil nails at rates exceeding 1,800 LF per day on compatible geology. Spider excavators eliminate temporary access road construction on steep terrain.
Those technology advantages translate into schedule compression and cost certainty your estimating team can rely on when building bids that include geotechnical specialty scopes. When GSI prices a scope with our Soil Nail Launcher™, we're reporting production rates from hundreds of comparable installations — not estimating them.
