│ The Products Background │

Cable Bolts have been used extensively in underground mines since the early 1970's. A comprehensive review of cable bolt performance in the early 1980's indentified that load transfer between plain strand and grout was often ineffective and resulted in extensive rock mass failures. At that time, Birdcage strand was developed to improve the load transfer and was introduced into both Underground and Open pit Mines. There was a marked improvement in overall performance of cable bolt reinforcement due to the increase in effectiveness of load transfer. However, the method of manufacture of Birdcage strand was inefficient and in the late 1980's Neville Hedrick invented an automated method to produce Garford Bulbs™ in strand. In the two decades since that time, Garford Bulb™ has been manufactured and used economically and effectively for Ground Support Applications Worldwide.
