The roofs totalled an area of approxiamately 3500 square meters. The original waterproofing consisted of basic traditional built-up felt membranes laid over fibreboard on a Vapour Control Layer, to a profiled metal roof deck.
The client had been working closely with Icopal in the UK and Europe to establish a cost effective solution to the many problems that Fords have been experiencing with their flat roofs.
The material chosen was Icopal Universal. A single Ply POCB membrane with good green credentials being fully recyclable. It is self finished, reinforced with glassfibre and polyester and tough enough to be walked upon. The use of heat was a major factor as Fords were insistent that there should be no naked flames used.
The specification adopted for these roofs was to first prepare the existing waterproofing by removing the bedded stone chippings. An Icopal Recovery Board was then mechanically fixed through to the profiled metal deck.
Icopal Universal was then loose laid and mechanically fixed along the head and side laps.
All lap welding was carried out using the Icopal Firesmart flam free heat welders.
The contract was completed on time and to the complete satisfaction of Fords.
