Draped Mesh Systems in California

Steep and overhanging rock faces along Big Sur, Laguna Beach, and the I-5 Grapevine release material that ditches and berms cannot contain. Access Limited's draped mesh systems guide falling rock to controlled collection zones — protecting California's most critical coastal and mountain corridors.

Controlling Rockfall on California's Steep Faces

Steep and overhanging rock faces along Highway 1 along Big Sur, PCH through Malibu, I-5 through the Grapevine, and SR-1 near Laguna Beach release material that conventional containment cannot capture. Coastal metamorphic rock, Franciscan Complex mélange, and fire-weakened hillsides produce rockfall trajectories that bypass ditches and berms — demanding a system that controls the fall path from the source to a managed collection point.

Draped Mesh Systems Solutions for California

Access Limited designs and installs draped mesh systems across California — each engineered for the slope height, face geometry, and rockfall volume specific to the installation site.

Standard Draped Mesh

Standard draped mesh is anchored along the slope crest with a horizontal cable and allowed to hang freely over the rock face. Falling material is captured between the mesh and the slope surface and guided by gravity to a collection zone at the toe.

  • Crest-anchored with horizontal support cable and vertical anchor bolts
  • Free-hanging drape allows rock to migrate downslope in a controlled manner
  • Toe collection zone sized for the anticipated rockfall volume and maintenance cycle

Anchored Draped Mesh

Anchored draped mesh combines the drape concept with intermediate face anchors — reducing mesh billowing on tall slopes and limiting the distance individual blocks can travel before being arrested.

  • Intermediate anchors at engineered spacing based on slope height and block size
  • Reduced mesh deflection compared to free-hanging systems
  • Appropriate for tall slopes where unanchored drape would create excessive bulging

High-Tensile Draped Mesh

High-tensile draped mesh uses steel wire with higher break loads than standard galvanized mesh — enabling the system to handle larger blocks and higher rockfall energy without mesh failure.

  • High-tensile steel wire with break loads exceeding 1,770 MPa
  • Engineered for large block sizes and high-energy rockfall zones
  • Extended service life in California's climate conditions

With an office in Oceano, Access Limited maintains permanent California-based crews ready for rapid deployment.

Our Installation Process

Every project follows the same disciplined workflow — adapted for the specific technique and site conditions.

Step 1

Field Investigation

Engineers assess the slope face, identify failure modes, document rock mass quality, and determine the catchment geometry and traffic exposure.

Step 2

Solution Engineering

The selected system is specified to match the documented conditions — every element is sized for the energy, volume, and geometry of the actual site.

Step 3

Staging and Mobilization

Equipment and materials are staged for efficient installation — minimizing the project footprint and time on the active corridor.

Step 4

Build and Verify

Installation proceeds according to the engineering plan with quality verification at every critical hold point.

Maintenance

Ongoing inspections and scheduled maintenance preserve system capacity and extend service life.

Why California Chooses Access Limited for Draped Mesh Systems

  • Purpose-Built EquipmentSpider Excavators position along the slope crest and face to install draped mesh anchor systems — working on terrain where crane access is impossible and rope-access alone would be prohibitively slow.
  • Rockfall Specialists, Not Generalists — Every Access Limited crew is trained specifically for steep slope and rockfall work. This is not a side service — it is the entire company.
  • Engineered Solutions — Every draped mesh systems installation in California is designed by engineers for the site-specific conditions — not selected from a generic product catalog.
  • 24/7 Emergency Response — When a rockfall emergency demands immediate draped mesh systems deployment on a California corridor, Access Limited mobilizes with the specialty equipment and trained crews to respond.

Landslide Repair for Infrastructure in California

“I would like to thank you and the county for repairing the road slide on Dunne avenue. The repair is excellent and the contractors were very efficient and skilled. You personally did a great job of providing information about the status of the project. My family appreciates your efforts.”

Emergency Rockfall Mitigation for Mining Operations

I recently interacted with some of your rockfall division guys. I have never seen an outfit as competent on safety measures nor any contractors who worked as hard as your guys do. During the work, I was in a room with your guys and some other contractors, and your guys were head and shoulders above the rest in all aspects.

Slope Stabilization for Mining Operations in California

Your crew finished up yesterday afternoon, leaving our slope in good shape. They worked safely, were responsive and enthusiastic, and hard-working. I'd be happy to have any of these guys on a future project with [our company].
