IKO Polymeric and contactor, FK Group have completed a roofing project for one of the biggest online grocery centres in the world – in under four months. This incredibly tight deadline was met with minimal material waste, thanks to a number of innovations developed specifically for the project by both companies.

The new fulfilment centre for premium British online supermarket, Ocado, is based in Erith, Kent which will handle 200,000 orders a week and represents £185 million local investment.

The project was completed in 4 months, a very short construction programme for a large – 48,000m2 – and challenging roofing project.

IKO Polymeric, the UK’s only single ply manufacturer, delivered several innovative solutions to complete the job with minimal waste.

Steve Hall, Managing Director of FK Group, comments: “IKO Polymeric demonstrated its usual proactive approach with innovations such as bespoke roll lengths and specific membrane overlap positioning allowing significant efficiencies to be achieved on site.”

Standard length membrane is typically 20 linear metres which then has to be cut or extended (by fixing additional sections on) to fit the required dimensions. IKO Polymeric manufactured its IKO Amourplan PVC single ply membrane in bespoke rolls of 22.35, 19.20 and 8.00 linear metres to reduce waste and installation time for this project.

Another first was manufacturing half the rolls with the membrane overlap positioned on the opposite side to the other rolls. This 50/50 split meant the contractor could use two teams working simultaneously on either side of the ridge, rolling the membrane out in the same direction. Usually one team works on one side at a time.
