The Dunlop Reocable Connector


The Dunlop Reocable Connectors are used to reduce the need for protruding reinforcing from precast concrete elements. These protruding reinforcing rods often are bent away so that the element can be safely moved, and then re-straightened on site so that they can be used to transfer the loads into the structure. Often these starter bars are replaced by threaded couplers which may be expensive to install.

The "Reocable" is a new word made by putting "Reo" (Reinforcing), and "cable" together. The Reocable is made from 1770 MPa steel and is wound to an 11mm dia cable with lots of ridges for superior adhesion. It has a typical tensile strength of 94.5kN and is made in an ISO9001 factory.

Dunlop Reocable Connector
A very strong and versatile precast connection for..

  • Connecting precast to in situ concrete.

  • Improving construction time and costs on site.

  • Providing more ductility at connections.

  • Replacing low strength bendable reinforcing.

  • Connection loads up to 800kN.

  • Transferring seismic loads.

    How does it work?


    A plastic void former is cast behind the reinforcing mat or tendons of the precast element. The Reocable then passes behind this reinforcing through the void former and is lapped to the in situ reinforcing. After the in situ slab has been poured the void former is grouted to protect the cable from moisture. When the structure moves due to an earthquake or other large forces the Reocable must pull through this reinforcing, which it is very difficult for it to do.


    Where to use?


  • Anywhere a starter bar is likely to be used.

  • The base of wall panels.

  • At intermediate floor levels.

  • At beam - column joints.

  • To increase the use of precast and speed up construction on site.

  • To overcome access issues on the construction site.



  • Foot of panel, intermediate floor, column-beam positions.


    Using the Dunlop Reocable


    The Dunlop Reocable Connectors are placed in the precast panel at the factory or the tilt up site. The connector is always flush with the surface as they are made to each individual size of precast element. After being delivered to the building site the precast element is positioned as required and the plastic of the void format is broken away to expose the void. Thread the Reocable as required and grout the cavity of the void former using the exposed grout tubes.
