Overview

Alfresco Floors supplied an NHBC Accepts certified non-combustible decking and support pedestals system for the roof terrace at New River Head, a historic site adjacent to Sadler’s Wells Theatre in London that has been transformed into apartments.

Originally the London terminus of the New River, an artificial watercourse opened in 1613 to supply water to the city. Subsequently the site also became the HQ for the New River Company, the owners of the New River, and for its successors, the Metropolitan Water Board, Thames Water Authority, and Thames Water plc.

Following relocation of most of the operational and administrative functions of the site, it is now largely a residential estate, with apartments in a mixture of repurposed existing and new buildings surrounding a private garden area on the site of the old filter beds.

Work undertaken

Alfresco Floors' sister company, Buzon UK Ltd, was contracted to install 35m2 of ZERODECK decking and A-PED pedestal system on a private roof terrace on one of the apartments.

With the natural fall of the roof, the void varied from 130–170mm so the A-PED was the ideal choice with its integrated slope correction functionality and wide load-spreading base, which allowed installation directly on top the waterproof membrane.

ZERODECK was clip-fixed to the A-PED-JOIST to give a perfect finish.

The client required steps from the access door down to the terrace so the installation team attached ZERODECK boards to a frame constructed from the REIF Duralink fire-proof flooring sytem, surface-mounting the fascia boards and clip-fixing the steps.
