UniPass Static Bolt

The UniPass Static Bolt is intended for use in static rock conditions. The bolt comprises a fully threaded hollow bar.

The UniPass Static Bolt can be installed in self-drilling mode, using a sacrificial drill bit (one step method) with the drill bit welded to the bolt, which minimises the annulus around the bolt, providing optimal bonding and reducing grout consumption.

A range of cross and button drill bits is available.

The bolt can also be installed in pre-drilled holes.

The grouting agent (CarboThix resin or cementitious grout) is injected through the central hollow section of the bolt into the borehole and fills the annulus between the bolt and the borehole wall.
