How to work

        Assess the ground conditions thoroughly.

        Bore a hole based on the bolt's diameter and length, ensuring it's 200mm to 500mm shorter than the bolt itself.

        Fix a breather tube along the entire length of the bolt, allowing it to extend approximately two meters from the hole.

        Affix roughly one meter of grout tube to the cable bolt's end, leaving enough excess to connect to the pump.

        Place the cable bolt into the hole and seal it to prevent grout loss during pumping.

        Link the grout tube to the pump and submerge the breather tube in a water container. Start pumping and observe air bubbles escaping in the water. 

        Once the hole is filled and bubbles cease, the grouting is complete.

        Tension the cable bolt after the grout has set.
