New build residential flats, steel frame concrete floor slabs and timber frame construction with 18mm plywood roof deck. The project was completed in a rolling construction program with the roof installed as soon as the deck was completed in order to protect interior construction processes.
All scaffolding and hoisting facilities were provided by the main contractor.
Owing to the large areas involved, manpower was tailored to meet the main contractors needs for each section of roof requiring to be made watertight.
The Sarnafil system met such requirements with ease due to the simple build-up and the limited plant and tools required for installation.
There was a need for speed in making the large areas of roof watertight. To achieve this a Sarnamatic machine was used to seal the long runs of laps. This mechanisation, in conjunction with normal hand welding to the details, ensured the integrity of the roof from start to finish. Generally, materials were brought to site as required with exception of bulk insulation.
