The 11,000m2 rooftop parking deck at the prestigious combined Waitrose and John Lewis at Home store in Basingstoke, Hampshire, has been completed by BriggsAmasco and Radflex Contract Services.

BriggsAmasco – appointed to the project by consultants Bowmer & Kirkland – initially developed plans to deliver thermal insulation, lightweight concrete and Permapark waterproofing and wearing courses on the roof deck parking area.

Given high client and tenant quality requirements, it was decided to use mastic asphalt, incorporating Radflex jointing systems. Mastic asphalt is durable – it is BBA certified in excess of 50 years – recyclable, carbon-zero, solvent- free, has excellent fire performance and is installed by trained craftsmen to ensure a quality finish.
