28mm Hollow Cable with grout tube centre

The Titan Bolt – a 28mm High Tension Hollow Cable is a hollow flexible cable bolt for top down grouting combined with in cycle resin cartridge point anchoring. The cable is compatible with a barrel and wedge anchoring system for pre-tensioning. Using a grouting lance grout can be pumped directly through the centre tube in the cable to exit near the top of the cable. There are bulbs continuously down the length for resin and grout anchoring.
