How to work
The nature of the ground must be evaluated.
Drill holes according to the diameter and length of the bolt, ensuring it's 200mm to 500mm shorter than the bolt itself.
Affix roughly one meter of grout tube to the cable bolt's end, leaving enough excess to connect to the pump.
Fix a breather tube along the entire length of the bolt, allowing it to extend approximately two meters from the hole.
Insert the High Strength Anchor Cable Bolt into the hole and seal it to prevent grout loss during pumping.
After the grout has set,tension the High Strength Anchor Cable Bolt.
Connect 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.
