Case study: A mixed development of residential, commercial and retail buildings incorporating refurbishment of existing structures and new build
'We have installed mastic asphalt in a variety of ways on this job, including the roof of the main residential block, walkways, private terraces and a ramp into the car park, 'says Bob Bolton of mastic asphalt contractor Coverite.
Terraces and the main residential block are of warm roof construction but, beneath the landscaping of a garden deck for residents, the centre is inverted-roof construction.
The deck's hard landscaping includes paving slabs, planters with palm trees and a perimeter pathway of coloured ceramic tiles let into the asphalt.
'Mastic asphalt is a tried and tested product, and it was clearly appropriate in this particular area, 'says project architect Sanjiv Gohil. 'At first-floor level there are various elliptical planters and lots of fiddly junctions, so we needed a formed material rather than something that needed to be cut. It's a great formable material, and once it's in you can forget about it for 20 years.'
The screed and insulation are laid to falls while the paving slabs are laid flat, the level difference taken out by plastic spacers.
'We also lined out all the planters and water features on the garden deck, 'says Bolton. 'The result is brilliant.The finishes and products used on top of the asphalt are unique and make it look tropical.'
