DYWI® Drill Hollow Bar System
The SystemThe DYWI® Drill Hollow Bar System is a self-drilling ground control solution used for Underground applications and in Civil Engineering. Underground, it can be used for bolting, foot piles, face stabilization, as forepoling element for pre-support, or as a lance for injection works.
The DYWI® Drill Hollow Bar System also features a wide range of applications in Civil Engineering such as rock and soil nails, micropiles, or ground anchors. The system features an “all in one” tool for drilling, flushing, post- or simultaneous grouting, and finally the load-carrying member itself Installations in weak ground and unstable borehole conditions represent no difficulty and are ideal for the application of the DYWI® Drill Hollow Bar System. DSI Underground has long-term experience in the design, development, manufacturing, testing, and distribution of the DYWI® Drill Hollow Bar System.
