Scarles Yard comprises a purpose built multi storey car park of concrete frame construction with ancillary integrated warehouse/workshop units located along its frontage.
With three levels, the car park provides 823 spaces for Aviva employees during the working week and is open for public use on Saturdays and Bank Holidays for a flat daily charge, being particularly popular when Norwich City FC play at home.
The top level of the car park is drained with 453 metres of Hauraton RECYFIX® PRO 100 – Type 75 channels in various run lengths. The channels are fitted with FIBRETEC® HEELSAFE 9mm slot gratings with a loading Class of C250. Made from PA-GF, the FIBRETEC® grating will not rust and has a slot configuration specifically designed by Hauraton R & D engineers to enhance the flow of water into the channel. The slots are super smooth, elliptical openings with the moulded bars having slightly raised triangular bosses along their outside edges. As well as providing an elegant appearance, the feature ensures surface water is directed into the slots. This configuration also helps eliminate any cross-flow over the grating and important consideration for this project.
The RECYFIX® channel component is made from 100 per cent recycled polypropylene (PP) and has an intake cross section of 372 cm². The FIBRETEC® grating are factory fitted on all channels. PRO accessories include a trash box, foul air trap, mud bucket, closed and DN 70/100 end caps.
Ken Burgess, Hauraton‘s Project Manager comments;
“As each one metre unit only weighed 3.4kg, the contractor, ATPS of Clacton on Sea, found the RECYFIX® PRO channels with their FIBRETEC® gratings easy to install in the concreted top level of the car park”.
