We are very sad to announce the passing of our former colleague, Cliff Billington.
Our new RVK 60P and TSS 60P offer greater flexibility, cost efficiency and environmental benefits.
We hadn’t typically gone the ‘specials’ route before. But, by investing a little upfront time to schedule our FERBOX requirements, we gained a smooth supply and installation process – without wastage or complication – and exceeded the programme demands of our slip-formed cores.
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.
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.
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.
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.
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.
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!
