Cascade volcanic soils and Puget Sound glaciomarine clay create persistent slope instability along corridors like I-90, SR-14, and US-2. When slopes move, infrastructure fails — highways close, rail lines shift, and the cost of delayed action compounds.
Access Limited provides landslide remediation and Puget Sound bluff stabilization for WSDOT corridors engineered from site-specific investigation data.
Access Limited addresses slope instability across Washington with landslide remediation, soil nail wall systems, GCS® walls, steep slope erosion control, and horizontal drain systems — plus coastal, shoreline, and bluff stabilization each engineered for the specific failure mechanism along corridors like I-90, SR-14, and US-2.
Landslide stabilization addresses slopes that have already failed or are actively moving. Access Limited investigates the failure surface, determines the driving forces, and designs the stabilization that arrests movement on Washington terrain. Emergency landslide response is available 24/7.
Soil nail walls reinforce slopes by installing steel reinforcement into the soil mass with shotcrete facing. Access Limited Soil Nail Launcher installs nails at production rates that cut construction time on WSDOT corridors.
Geosynthetically Confined Soil walls provide engineered slope stabilization using reinforced soil lifts — cost-effective alternatives to traditional retaining structures where Washington soil conditions permit.
Steep slope erosion control prevents the progressive material loss that leads to failure. Access Limited designs surface water management, bioengineered protection, and armored drainage channels calibrated for Washington precipitation and soil erodibility.
Coastal stabilization, shoreline protection, and bluff stabilization protect Washington infrastructure from wave erosion, storm surge, and coastal retreat.
Horizontal drains relieve pore water pressure within the slope mass — often the single most effective stabilization measure available. Access Limited installs horizontal drain arrays based on measured groundwater conditions at each Washington site, reducing the pore pressure that drives the majority of slope failures. UAS-based geohazard assessments support drain design with high-resolution terrain data.
Soil Nail Launcher — Proprietary pneumatic nail installation at production rates that cut construction time on Washington corridors.
