Driftless Area dolomite and towering loess formations along corridors like US-52, US-18, and Missouri River bluffs create slopes where conventional drill rigs cannot operate. Access Limited eliminates that constraint with Spider Excavators and rope-access crews.
Access Limited navigates Iowa 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 US-52, US-18, and Missouri River bluffs.
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.
Rope-access certified drilling crews work on vertical and near-vertical faces across Iowa — drilling precise anchor patterns where no machine can be positioned.
When the site is in a steep canyon or behind terrain that eliminates conventional access, difficult access drilling bridges the gap.
Some Iowa sites are hours from the nearest road. Remote access drilling deploys self-sufficient crews that traverse the terrain.
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 Iowa.
See why Iowa DOT, railroad operators, and Army Corps of Engineers trust Access Limited for steep slope drilling in Iowa.
Access Limited provides Spider Excavators and rope-access crews reach every steep slope across Iowa.
