VersiJack® pedestals used on the rooftop of the Office of Estate and Development (OED) at the National University of Singapore created a raised paver deck and walkways around Elmich Extensive Green Roof plots in shallow planter boxes on the roof garden. The cavity space beneath the raised decking in combination with insulation provided by the green roof minimizes heat transfer from the rooftop to the office space below.


Water drains away quickly from the paver surface through gaps into the cavity space beneath the raised pavers which also help to eliminate the forming of unsightly efflorescence on the paver surface.
