No need for injection equipment

The Lokset® system consists of an easily handled cartridge, containing a highly reinforced polyester
resin component, together with its catalyst, in accurately measured quantities.
The components are isolated from each other by a physical barrier which
prevents reaction between the components until required.
The cartridges are sausage-shaped and designed for rapid insertion into a range of borehole
sizes, where they may be readily pushed to the extremity at any angle above or below the horizon.
Therefore, optimum bolt anchorage in a wide range of rock or concrete strengths is easily achieved simply
by adjusting the length of the resin anchor zone.

No reaction takes place until the roof or rock bolt is rotated through the cartridge, mixing the components
and initiating the curing action. The chemical nature of the Lokset® cartridge allows the contents to be
easily mixed, yet minimizes resin runout after mixing is complete.

The mixed resin fills the annulus around the bolt. Standard “point” anchorages will be firmly interlocked
with the substrate and bolt within minutes.

The setting time of the resin components can be controlled. A combination of fast- and slow-setting
cartridges makes possible the simultaneous operation of anchoring, grouting and tensioning a rock bolt.
The simplicity of this method of anchoring/grouting eliminates the need for cumbersome injection
equipment.
