A purpose-designed ‘left-in’ component for easy forming of recesses in concrete walls (precast or insitu). Suitably sized to complement the sliding inner-sections of standard TSS & RVK Telescopic Connectors (all load ranges) prior to receiving cementitious grout-fill. Its design provides +/- 35mm (min) vertical tolerance and +/- 40mm (min) horizontally. The REDiBOX Permanent Recess Former is manufactured from durable and environmentally recyclable HDPE.

The embedded box element is heavily ribbed on all sides, comprehensively anchoring it into the concrete wall. The rear of the detachable face-plate has an inset perimeter rib, which provides a close fit to the box and which also maintains the shape of the recess former under concrete pressure. The unit is fully sealed, which ensures that the recess will be clean once the face-plate is removed. The face-plate can be nailed to timber moulds or shutters, the integral lugs (two on four sides) provide ample fixing points to tie-wire thAlternativelye unit to the wall reinforcement (ideal for slip-forms). The recyclable face-plate incorporates a central ‘soft-eye’ into which a hammer-claw can be inserted to pull and detach, revealing the clear recess.

Invisible Connections AS has been in contact with the South Korean company “New Korea Trading (NKT)” since June 2017. In early November, our two companies entered into an agreement. In the picture you see Managing Director Svein Berg together with Vice President J. U. Cho confirming the written agreement with a handshake.

We are proud to be a part of this project. “The Hub” is the innovation center at Manchester Science park, it’s located at the heart of the science park. It’s 6500 m² over 4 story. The architect and designer wanted corbel free connections between beams and columns, and our UK partner Invisible Connections ltd did a great job selling inn BSF connectors.

This is what the precaster ABM Precast solutions wrote about the project:

The Innovation Centre, at the centre of Manchester Science Park is a concrete framed, BREEAM Excellent building providing office and low level laboratory accommodation over four floors set around a central atrium, as well as café and restaurant facilities, a gym, with meeting, conferencing and networking spaces.

Supply of precast building frame components to suit the building’s unique trapezium plan form including 235 beam and column components using the ‘Invisible Connection’ jointing system.
