The Sinorock is particularly suitable for soils that do not allow for open-hole drilling (i.e. granular soils
that are collapsible in nature). In such cases, drilling with a grout fluid serves the purpose of flushing spoils from the borehole and
prevents looser, surrounding material from collapsing due to the higher relative density of the grout. Sinorock self drilling rock bolt
System should be considered on any project requiring fast production that would otherwise need to involve a casing system in order to
maintain borehole stability.
