Lake Agassiz expansive clay and North Shore basalt coastal bluffs create persistent slope instability along corridors like US-61, TH-169, and Lake Superior North Shore. When slopes move, infrastructure fails — highways close, rail lines shift, and the cost of delayed action compounds.
Access Limited provides North Shore bluff stabilization and soil nail walls for MnDOT engineered from site-specific investigation data.
Access Limited provides engineered slope stabilization across Minnesota, where lake agassiz expansive clay and north shore basalt coastal bluffs create conditions along US-61, TH-169, and Lake Superior North Shore that demand solutions from site-specific investigation data.
Landslide remediation is Access Limited core slope capability — investigating, designing, and constructing repairs from emergency responses to permanent remediation across Minnesota.
Soil nail walls reinforce the existing slope mass with steel nails and shotcrete facing. GCS® walls build reinforced earth structures where traditional walls are cost-prohibitive. The Soil Nail Launcher accelerates installation. Spider Excavators access the steep faces where conventional equipment cannot operate.
Engineered erosion control protects Minnesota slopes from progressive material loss — surface water management, bioengineered treatments, and armored protection sized for site conditions.
Coastal, bluff, and shoreline stabilization protect Minnesota infrastructure from marine erosion and storm surge.
Horizontal drains are the most efficient way to reduce pore water pressure in Minnesota slopes — often converting an unstable slope to a stable one with drainage alone. Access Limited installs drain arrays based on measured piezometric data at each site. UAS assessments provide high-resolution terrain data to support drain design.
Soil Nail Launcher — Proprietary pneumatic nail installation at production rates that cut construction time on Minnesota corridors.
Spider Excavator Access — Reaching steep, unstable slopes where conventional equipment cannot operate.
Design-Build — In-house engineers design, Access Limited crews construct — one contract, one team.
Horizontal Drain Expertise — Pore water pressure reduction through measured piezometric data-driven drain arrays — the most effective single stabilization measure available.
Coastal Expertise — Fiberglass soil nails and armoring adapted for saltwater environments.
