London - UK-based developer Stanhope is exploiting SPS (Sandwich Plate System) technology, based on steel plates bonded with a layer of polyurethane elastomer, to replace concrete flooring on a new building at its Chiswick Park, London, development.
The group claims the process can reduce construction time by 35 percent, and that the pre-fabricated composite floors used within a steel-frame building are 75 percent lighter than concrete.
SPS technology, owned and developed by UK group Intelligent Engineering, consists of two steel plates bonded to a solid polyurethane elastomer core. The technology has been used in ship and bridge deck repair and is also aimed at the shipbuilding market, where its strength combined with light weight offer considerable advantages.
"We have three distinct applications for this sector [civil engineering] - SPS Terraces, SPS Floors and SPS Bridges. We work closely with Elastogran (a BASF unit) and they supply the polyurethane for SPS," said Intelligent Engineering marketing manager, Polly Simpson. Asked if the future of SPS was in the civil engineering sector Simpson said, "it is one element of what we do. Our future is to continue to develop and market applications for SPS in the maritime and built environment."
Stanhope said the new system adapts the SPS technology, currently used on a number of infrastructure products such as stadiums, bridges, and ship's decks. The developer added that it is, "set to be deployed on a major commercial property development for the first time."
