glacial till on steep notch walls and thin residual soils create persistent slope instability along corridors like I-93, US-302, and NH-16. When slopes move, infrastructure fails — highways close, rail lines shift, and the cost of delayed action compounds.
Access Limited provides notch corridor slope stabilization and soil nail walls for NHDOT White Mountain passes engineered from site-specific investigation data.

Access Limited provides engineered slope stabilization across New Hampshire, where glacial till on steep notch walls and thin residual soils create conditions along I-93, US-302, and NH-16 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 New Hampshire.
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 New Hampshire slopes from progressive material loss — surface water management, bioengineered treatments, and armored protection sized for site conditions.
Coastal, bluff, and shoreline stabilization protect New Hampshire infrastructure from marine erosion and storm surge.
Horizontal drains are the most efficient way to reduce pore water pressure in New Hampshire 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.
