Every rockfall event starts with a block that was loose on the slope face. Along Highway 1 along Big Sur, PCH through Malibu, I-5 through the Grapevine, and SR-1 near Laguna Beach, Coastal metamorphic rock, Franciscan Complex mélange, and fire-weakened hillsides produce weathered, fractured rock faces where loose blocks, wedges, and slabs accumulate over time. Scaling removes this material proactively — reducing the frequency and severity of rockfall events before they occur.
Access Limited performs mechanical, manual, and remote scaling operations across California — using Spider Excavators, rope-access crews, and controlled blasting to address every scale of loose rock removal.
Mechanical scaling uses Spider Excavators to remove loose rock from steep slope faces with hydraulic breakers, buckets, and ripping tools. The Spider Excavator's ability to walk on slopes exceeding 60 degrees makes it the most productive mechanical scaling tool available.
Manual scaling uses rope-access technicians to hand-scale individual blocks, wedges, and loose material from exposed rock faces. This method is used where precision is required or where equipment access is not feasible.
Remote scaling uses long-reach equipment or controlled blasting to remove large unstable masses from slope faces without placing personnel directly on the face.
Controlled blasting removes large rock masses that cannot be addressed by mechanical or manual methods. Access Limited coordinates controlled blasting operations with full traffic management and safety planning.
Oversized boulders that have already detached but are too large to handle intact require breaking before removal. Access Limited uses hydraulic breakers and controlled methods to reduce boulders to manageable sizes.
With an office in Oceano, Access Limited maintains permanent California-based crews ready for rapid deployment.
