A limestone quarry in Kentucky experienced rock falls near the high walls supporting its crusher facilities. Low-capacity draped mesh that had been placed in the area more than ten years ago was raveling, and large blocks were threatening not only the safety of the plant workers, but the plant facilities themselves. GeoStabilization’s rockfall team worked in conjunction with the client and the client’s consulting engineers to develop a plan to spot bolt some of the dangerous overhangs and reconstruct the draped mesh using Geobrugg’s high capacity TECCO® mesh. By using GeoStabilization’s purpose-built, limited-access wagon drills for the tight access site, our team’s price was less than half of those proposed by competing teams.
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.
