An industrial tramway manufacturer required two tower foundations for a new tramway in rugged mountain terrain. Traditional construction equipment could not reach the tower locations. Our Rockfall Remediation Technicians (RRTs) drew up a plan to install a series of high-capacity drilled SuperMicropiles™ high in the peaks. Crews and purpose-built limited access drill rigs were mobilized using helicopters, and the innovative approach resulted in minimal site disturbance.
In the 1970s, a massive rockslide buried Interstate 81 in Montgomery County, VA while it was being constructed. The mountain of debris took months to clear. More recently, VDOT engineers and geologists noticed active movement near the historic slide, and proactively began an emergency rock slope mitigation effort.
