The Sinorock® SDA system offers self-drilling anchor bolt where the central hollow threaded reinforcement bar acts as both final reinforcement in the completed anchor and as the drill rod during installation. The SDA system is installed with sacrificial drill bits under a grout flush. In granular deposits in particular, the impregnation of grout into the surrounding ground significantly enhances the geotechnical capacity of the anchor. Large slabs of concrete and rock can also be readily drilled. These anchors work well as both tension and compression tiebacks and can be installed horizontally to meet any tieback or anchoring design criteria.
