GeoStabilization International (GSI), Access Limited, and RoadGuard together form a leading infrastructure solutions platform dedicated to protecting people and strengthening critical infrastructure across North America and New Zealand.
GSI is the premier geohazard mitigation firm specializing in emergency slope stabilization, landslide repair, grouting, and micropiles through innovative design-build delivery. Access Limited brings over a century of steep-slope expertise and operates North America’s largest fleet of spider excavators, delivering complex rockfall and geotechnical solutions in the most challenging environments. RoadGuard, founded in 2024, unites industry-leading roadway safety companies providing guardrail, bridge railing, highway signage, fencing, and specialty fabrication services.
Across all our businesses, we are driven by innovation, extreme ownership, technical excellence, and a relentless commitment to measurable results that improve safety and infrastructure resilience.
At GeoStabilization International, deep foundation, small diameter drilling is mission-critical work. We operate in unstable slopes, emergency geohazard conditions, and structurally sensitive environments where installation accuracy, casing integrity, and ground control determine project success.
We are seeking casing drilling specialists who understand that this work is not about spinning steel — it is about installing structural systems correctly the first time.
