BALLASTED INSULATED

SINGLE PLY GREEN ROOF

REFURBISHMENT

SYSTEM OVERVIEW

The Fatra ballasted system can be implemented with a number of different types of ballast. Including pebbles, adjustable chairs/pedestals and pavers or even a floating timber deck can be used to ballast the PVC membrane system into place.

Depending on site specific requirements and objectives the membrane can be loose laid or mechanically fixed over the existing failed membrane which substantially reduces the overall project costs and risks associated with removing existing membranes and exposing the existing structure to water damage during this process.

Implementing a ballasted system can reduce cost depending on the method of application whilst providing protection to the PVC membrane from the harsh UV which will in-turn increase the life expectancy of the membrane. By implementing a ballasted system it covers the PVC membrane and can provide a very aesthetically pleasing finish.

GREEN ROOF | OVERLAYING FINISHES

Fatra Armour protection mat is loose laid over the Fatrafol PVC Membrane to protect the membrane from the drainage cell. Installation of Fatra Drainage cell is then installed with a filter fabric applied above the drainage cell prior to the installation of the green roof build up.

FATRAFOL 810v | REINFORCED PVC SHEET MEMBRANE

The Fatrafol 810v reinforced membrane is installed over the PIR insulation. The Fatrafol 810v is ballasted into place with the green roof build installed above

PIR INSULATION | FOIL FACED INSULATION BOARD

The PIR insulation is installed over the existing failed membrane and is ballasted into place with the green build up which is installed above the Fatra system.
