Summary

Raaft products were able to meet the demanding specifications of the rooftop terrace project at Drapers Yard which required porcelain tile paving and artificial grass to be installed on a raised pedestal system in a very unusual arrangement. Due to the location of the terrace, wind uplift and fire resistance also needed to be taken into account.

Context

The Drapers Yard redevelopment project involved converting a vacant building in Leeds’s historic industrial quarter into a medical facility, creating a 100-bed clinic, pharmacy and almost 300 highly-skilled scientific and healthcare jobs in the city.

The dramatic transformation of the building included a new façade, a rooftop terrace amenity space, a green sedum roof and new landscaping and planting on Marshall Street and Sweet Street.

Requirement

The rooftop terrace project required porcelain tile paving and artificial grass to be installed on a raised pedestal system in a very unusual arrangement.

Raaft products were able to meet the demanding specifications of this rooftop terrace.

Due to the location of the terrace, wind uplift and fire resistance also needed to be taken into account.

Work done

A Raaft support system comprised of Preventa® pedestals, joists and floor structure panels provided a stable, easily-constructed raised platform for the tiles and artificial grass.

The route of the pathways across the terrace required numerous small and angular tile cuts and for these, the floor structure panels provided a solid base that couldn’t be achieved with a standard pedestal system.

Outcome

Raaft’s almost invisible clip system prevents wind uplift yet allows tiles to be easily removed and replaced for inspection, repair and maintenance work.

All Raaft products used on the project are BRoof(t4) or BS-EN13501-5 fire-rated, ensuring full compliance with fire safety requirements.
