Schöck meets curved balcony challenge in Docklands

Schöck meets curved balcony challenge in Docklands

Schöck Isokorb structural thermal break for concrete-to-concrete applications has been incorporated in the curved balconies at Gateway Tower.

With its striking series of curved forms, Gateway Tower, just a few hundred yards west of the ExCeL Exhibition Centre at Royal Victoria Dock, is an intriguing example of modern urban design. The 73 metre high, 24-storey mixed-use scheme provides 161 spaciously designed apartments and penthouses, with office and retail space at ground level.

Each apartment features a terrace or a balcony. The design specifications on the project were demanding and the avoidance of thermal bridging at any of the critical connectivity points was key. To counter such problems, the Schöck Isokorb structural thermal break for concrete-to-concrete applications was incorporated – but there was an installation challenge or two.

The first being that there was a tight radius in which to position the thermal breaks, due to the unusual curved styling. The Isokorbs were supplied with alternating depths of rebar and concrete cover to the tension bars. This allowed the rebar in the Isokorb to sit underneath the internal slab reinforcement and not clash with the bars from the Isokorbs on either side of each unit. Schöck also had to create a bespoke unit for one of the balcony types, where a beam was introduced to the balcony to reduce the deflection of the slab.

In addition to concrete-to-concrete, the comprehensive Isokorb range from Schöck also offers concrete-to-steel solutions, a modular product for steel-to-steel applications – and even a maintenance free alternative to wrapped parapets.

When any Isokorb product type is incorporated into residential buildings, the required fRsi value is always comfortably met and the range also complies with the Government Standard Assessment Procedure, SAP 2012. Products meet full compliance with the relevant UK building regulations, have NHBC approval and offer LABC Registration. There is also the security of independent BBA Certification.
