Anchors and Rock Bolts - GRP Anchors and Rock BoltsGRP Anchors and Rock Bolts are used as an alternative to conventional ground control elements made of steel. Thanks to the rapid development of production technologies and a higher amount of mechanical excavation, GRP systems have gained importance in underground construction around the world.
Fields of application of GRP Anchors and Rock Bolts range from cuttable rock bolts for underground coal mining or ground control for mechanical excavations to injection lances or forepoling.
DSI Underground provides a diversified portfolio of GRP systems for various applications in Mining, Tunneling, and Civil Engineering which is completed by longtime experience in the production and application of GRP Anchors and Rock Bolts.
