I’ve used your services on my last three projects (telescopic connectors for precast and continuity strip for in-situ). You’re very good at accommodating site demands for lead-in times and value competitiveness. Very happy with the service I’ve received on all three projects and hope this relationship will continue on future developments.

We have completed installation of our stairs in both cores, using TSS connectors. Everything went smoothly, quickly and easily. The new anti-uplift brackets have done the job perfectly.

There’s no drilling, which of course involves manpower. And every drilling detail comes with resin, which is not cheap. The safety hazard of silica dust is an important consideration. Eliminating all of this gives the contractor a great advantage.

We were thinking how we could give the architect what they wanted: a finished landing with a shadow gap all around. We used the telescopic connection system from Invisible Connections, which made it a lot easier, both to install the wall recesses and to install the stairs.

Thank you for sending the calculations and installation advice. The new calculation software looks great. Very clear, user friendly and with more design checks than the previous version. It’s a pleasure to see how you are constantly improving.

Invisible Connections are an outstanding company to work with. Between Ross in sales and Derek on the technical side of things, iC have an offering which the rest of the market would do well to get close to. I can’t credit these two individuals enough for the support they have given me for both standard and bespoke FERBOX connections – some rather more complex than others!

In a slipform core, having several couplers in a box actually makes it easier and quicker to find. Just take off the lid and the couplers are exposed without any damage.

An issue with slipform is dragging. We always try to find solutions for fixing the casting elements robustly. Singular couplers are flimsy (just tied individually to the wall rebar), but coupler boxes are more robust and can resist that drag. COUPLER CADDi is a really good solution for slipform systems.

As specialists in precast concrete car park construction, we use telescopic connectors for many key applications. Particularly, the BSF system helps us to construct a ‘modern’ frame without cumbersome corbel supports and enables rapid assembly on site. The technical back-up provided by Invisible Connections provides us with added reassurance.

Telescopic connectors provide us numerous advantages for precast stair installation. Apart from improved time and efficiency, the health and safety gains over traditional support methods are a key driver to satisfy our own needs, as well as those of our clients.
