When Conventional Equipment Cannot Reach the Site

Cascade volcanic soils and Puget Sound glaciomarine clay along corridors like I-90, SR-14, and US-2 create slopes where conventional drill rigs cannot operate. Access Limited eliminates that constraint with Spider Excavators and rope-access crews.

Steep Slope Drilling Capabilities in Washington

Access Limited navigates Washington most challenging terrain with Spider Excavators and rope-access certified drilling crews — installing anchors, bolts, nails, and barrier foundations on slopes where conventional drill rigs cannot operate along corridors like I-90, SR-14, and US-2.

Spider Excavator Drilling

Spider Excavators walk on slopes exceeding 60 degrees — reaching work faces that would require road construction for any conventional rig. Access Limited operates the largest Spider Excavator fleet in North America.

Ropework Drilling

Rope-access certified drilling crews work on vertical and near-vertical faces across Washington — drilling precise anchor patterns where no machine can be positioned.

Difficult Access Drilling

When the site is in a steep canyon or behind terrain that eliminates conventional access, difficult access drilling bridges the gap.

Remote Access Drilling

Some Washington sites are hours from the nearest road. Remote access drilling deploys self-sufficient crews that traverse the terrain.

Purpose-Built Drill Rigs

Access Limited operates purpose-built limited access drill rigs fabricated for steep slope and confined conditions.

Steep slope drilling supports rockfall mitigation, slope stabilization, shoring, and ground improvement across Washington.

How Access Limited Reaches Difficult Terrain

Every steep slope project starts with access assessment.

Step 1

Access Assessment

Engineers evaluate terrain, slope angle, and access constraints to select the right equipment.

Step 2

Drilling Plan

Hole locations, depths, angles, and equipment configuration are determined by the site.

Step 3

Spider Excavator Deployment

Spider Excavators walk to the work face — no access road required.

Step 4

Drilling Execution

Anchors, bolts, nails, and foundations installed to specification on the steep face.

Verification

Completed drilling verified against design specifications before handoff.
