Soil Nail Retaining Wall

This project was an emergency landslide remediation for UGI Energy Services and PennDOT. Clearwater Geotechnical acted as the specialty Geotechnical subcontractor to New Enterprise Stone & Lime Co., Inc., and successfully arrested and stabilized the landslide via installation of a 2500 sf soil nail wall including 102 soil nails utilizing the Williams Geo-Drill Injection Anchor System.  The shotcrete facing varied from 4 inches up to 30 inches thick with a design strength of 4,000 psi. The project was constructed during the winter utilizing ground heaters and blankets on a fast track basis adjacent to live traffic in 3 weeks.
