DCPTen Double Corrosion ProteCteD
23.5mm Flexi-bolt
The DCP cable bolt is the flexible cable version of a tried and proven solid DCP bolt. By
utilising a barrel and wedge supported 23.5mm cable with a patented DSI grout bell, the
resin anchored cable can be post grouted via the top down method.
The barrel and wedge is pre-tensioned to the cable bolt at DSI and shipped ready to install
with a compatible dome plate.

Finally, an alternate top down groutable cable
Drilling - 1. Drill Ø45mm to Ø50mm hole (consult DSI for appropriate length).
Installation - 2. Insert a resin cartridge and gently push it all the way to the back of the
hole. Cable ties can be used to hold the resin in position at the back of the hole.
Resin mixing - 3. After insertion of the chemical resin, the DCP-Ten is rotated through
the chemical resin at maximum rpm until the DCP-Ten reaches the back of the hole,
continue spinning as per directions (marked on the resin anchor box).
Tensioning - 4. The tensioner unit is connected to the DCP-Ten cable bolt and tension
applied.
Grouting - 5. The DCP-Ten can be post grouted immediately or at any time later using
grouting equipment.

> A sleeve of HDPE encases the cable from the resin boundary down to the grout bell providing a barrier to combat the effects of corrosion.
> The HDPE sleeve has deformations to improve load transfer at the cable to rock interface when fully grouted.
> Top down grouting is achieved by pumping through the side of the grout bell and up the inner side of the HDPE sleeve allowing grout to flow from the top down the outer annulus.
> As the 23.5mm cable is a standard Hi-Ten of compact strand with minimal void space a more stable surface is provided for tensioning.
> The grout bell assembly collar and segmented wedge can sustain collar loads of between 52 and 55 tonne.
> The DCP-Ten is delivered preassembled with barrel and wedge ready for installation.
