Hollow steel tendons with the SINODRILLS T thread are used when the bond behavior is critical for the level of safety required. The advantage of the self drilling system (SDA / IBO) system are:
◆ Variable applications
◆Simple to install in unstable boreholes
◆Especially advantageous in rocks / soils with low cohesion
◆Grouting assured over full depth of borehole
◆Stabilization of the borehole with cement slurry
◆No stalling when drilling across clefts
◆Dynamic grouting during drilling
◆Drilling and installation in one operation
◆No need to extract drill strings
