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. GSI®’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 GSI®’s purpose-built limited-access wagon drills for the tight access site, the team’s price was less than half of that proposed by competing teams.
A Mid-Atlantic state’s Department of Transportation (DOT) and its historical preservation group wanted to repair and rehabilitate a failing rock wall within a town in Appalachia.
